==== BitLocker ====
 
==== BitLocker ====
* '''''BitLocker_PoolPartUnlockDetect''''' - Set to True to add support for BitLocker encrypted pool parts. Adds a small overhead and is Disabled by default You must still manually unlock the drives, unless the system disk is also encrypted and configured to auto-unlock the other drives.
+
* '''BitLocker_PoolPartUnlockDetect''' (Default: Stable: "False", Beta: "True") - Set to True to add support for BitLocker encrypted pool parts. Adds a small overhead and is Disabled by default You must still manually unlock the drives, unless the system disk is also encrypted and configured to auto-unlock the other drives.  
  
 
==== CoveFS ====
 
==== CoveFS ====
* '''CoveFs_AsyncCriticalThreads''' - How many threads to use for critical asynchronous tasks. Asynchronous tasks are used throughout CoveFS to parallelize various file system operations. In particular, this affects how many disks in the pool are accessed at the same time when we need to query all the disks for some information.
+
* '''CoveFs_AllowMixedFilesystems''' - (Beta: "False") - Allows mixing of ReFS and NTFS pools.  For compatibility, this should be left off.  Enabling this is useful for migrating your pool from NTFS to ReFS or from ReFS to NTFS.
* '''CoveFs_AsyncNormalThreads''' - How many threads to use for normal asynchronous tasks.
+
* '''CoveFs_AsyncCriticalThreads''' (Default: Stable: "8" Betas: "2")- How many threads to use for critical asynchronous tasks. Asynchronous tasks are used throughout CoveFS to parallelize various file system operations. In particular, this affects how many disks in the pool are accessed at the same time when we need to query all the disks for some information.
* '''CoveFs_BoostNetworkIoPriorityWrite''' - Boost the priority of write network I/O.
+
* '''CoveFs_AsyncFindFilesThreads''' - (Default: "8") - How many threads are used for finding files in pool parts (used for measuring, duplication checks, balancing, and dpcmd commands.  
* '''''CoveFs_BypassNtfsFilters''''' - This bypasses the normal NTFS filters and instead forwards the I/O directly to the NTFS disks, instead of through the filters. CoveFS (the drive pool) respects these filters, but some filters may freeze or crash if forced to process the same file more than once. This should be left enabled unless instructed otherwise.
+
* '''CoveFs_AsyncNormalThreads''' (Default: "20") - How many threads to use for normal asynchronous tasks.
* '''CoveFs_EfsEnabled''' - Enable experimental EFS support on the pool.
+
* '''CoveFs_BoostNetworkIoPriorityWrite''' (Default: "False") - Boost the priority of write network I/O.
* '''CoveFs_LogSizeMB''' - The binary kernel log size. 100MB can be from a few minutes to 10 minutes worth of logs, depending on I/O activity. The kernel binary log records every operation on the pool in a high performance and compact log file.
+
* '''CoveFs_BypassNtfsFilters''' (Default: "True") - This bypasses the normal NTFS filters and instead forwards the I/O directly to the NTFS disks, instead of through the filters. CoveFS (the drive pool) respects these filters, but some filters may freeze or crash if forced to process the same file more than once. This should be left enabled unless instructed otherwise.
* '''CoveFs_OpenByFileId''' - Open by file ID support. This allows applications to open any file on the pool by its unique file ID, instead of the file name. This feature is '''required by the NFS server'''. When enabled, the pool will keep track of every file ID that it gives out in page-able memory (memory that is saved to disk and loaded as necessary).
+
* '''CoveFs_EfsEnabled''' (Default: "False") - Enable ''experimental'' EFS support on the pool.
* '''CoveFs_Oplocks''' - Enable / disable file system oplock support.
+
* '''CoveFs_IsDiskRemovable''' (Default: Stable: "True"; Beta: "False") - Should the pool drive be a removable drive? Defaults to False. This setting takes effect after a reboot.
* '''CoveFs_ReadStripingBlockMode'''' - Switch to the read striping block mode algorithm when sequential read access is used.
+
* '''CoveFs_LogSizeMB''' (Default: "100MB") - The binary kernel log size. 100MB can be from a few minutes to 10 minutes worth of logs, depending on I/O activity. The kernel binary log records every operation on the pool in a high performance and compact log file.
* '''CoveFs_ReadStripingBlockModeNoCache''' - Disable the NT read ahead cache when using read striping block mode.
+
* '''CoveFs_MeasureBackgroundTaskPriority''' - (Default: "True") - Changes the priority at which the measuring pass is ran at.  Enabling this runs the task at the "idle" process, and disabling it runs it at a normal priority as specified by "DrivePool_BackgroundTasksPriority" .  The priority can be temporarily boosted in the UI.  
* '''CoveFs_ReadStripingStripeSize''' - The stripe size to use for reading in block mode.
+
* '''CoveFs_OpenByFileId''' (Default: "True") - Open by file ID support. This allows applications to open any file on the pool by its unique file ID, instead of the file name. This feature is '''required by the NFS server'''. When enabled, the pool will keep track of every file ID that it gives out in pageable memory (memory that is saved to disk and loaded as necessary).
* '''CoveFs_ReparsePointsEnabled''''' - ''Experiemental''. Enables Reparse Point (symbolic link) support on DrivePool drive. As for Build 320, does not work properly.
+
* '''CoveFs_Oplocks''' (Default: "True") - Enable / disable file system oplock support.
* '''CoveFs_ReportAsNtfs''' - Report as "NTFS" to most applications that ask.  
+
* '''CoveFs_ReadStripingBlockMode'''' (Default: "True") - Switch to the read striping block mode algorithm when sequential read access is used.
* '''CoveFs_SynchronizeDirectoryTimes''' - On NTFS, when creating a new file in a directory, the last write time of the directory that contains that file gets updated. In order to have CoveFS ensure that directory modification times are updated consistently, this needs to be enabled. There is a small real-time performance penalty for having this enabled. The algorithm that makes this work is multi-threaded and will benefit from multiple CPU cores.
+
* '''CoveFs_ReadStripingBlockModeNoCache''' (Default: "False") - Disable the NT read ahead cache when using read striping block mode.
* '''CoveFs_TracingEnabled''' - Enable user / kernel logging by default. This should be set to True for the beta test, just in case you run into problems and need to submit logs.
+
* '''CoveFs_ReadStripingStripeSize''' (Default: "1048576") - The stripe size to use for reading in block mode.
* '''CoveFs_TracingFlushS''' - When CoveFs_TracingEnabled is enabled, this sets flush to disk the interval. 0 will flush on every trace.
+
* '''CoveFs_ReparsePointsEnabled''''' (Default: "True") - Enables Reparse Point (symbolic link) support on DrivePool drive.  
* '''CoveFs_WaitForVolumesOnMount''' - Some volumes arrive late in the boot process so DrivePool will wait for all the volumes to arrive before allowing the pool drive to mount. The delay is adaptive, so it will be different for each system. Turning this off might shorten boot times, but is not recommended because it could expose a partially populated pool drive to system services that start right after booting.
+
* '''CoveFs_ReportAsNtfs''' (Default: "True") - Report as "NTFS" to most applications that ask.
* '''CoveFs_WaitForVolumesOnMountMs''' - How long to wait for all the volumes to arrive in MS.
+
* '''CoveFs_ReportAsRefs''' (Beta: "False") - Report as "ReFS" to most applications that ask.

 +
* '''CoveFs_SortedDirectoryQueries''' (Default: "False") - Enabling this option will pre-buffer and pre-sort all directory enumerations in the kernel. This has a major negative impact on directory enumeration performance and should only be enabled if directory enumerations must come back in a sorted order (normally the application performing the enumeration will sort the output for you).
 +
* '''CoveFs_SynchronizeDirectoryTimes''' (Default: "False") - On NTFS, when creating a new file in a directory, the last write time of the directory that contains that file gets updated. In order to have CoveFS ensure that directory modification times are updated consistently, this needs to be enabled. There is a small real-time performance penalty for having this enabled.

DrivePool.Service.config

You can tweak advanced settings in Stablebit DrivePool by editing a .config file in notepad.

The file is located in C:\Program Files\StableBit\DrivePool\DrivePool.Service.exe.default.config.

In order to put the file into effect, you will need to rename the .config file to DrivePool.Service.exe.config and restart the StableBit DrivePool system service (or reboot).

Any time you upgrade, or reinstall DrivePool, it writes an updated "default" config file, but leaves the current "DrivePool.Service.exe.config" alone so it doesn't alter any of your settings.

Editing the config file

Open the file in notepad. You will see an XML formatted file. If you're not familiar with XML then all that you need to know is that the values that you can change look like this:

<value>True</value>

You can change this line to:

<value>False</value>

The setting name is right above that line:

<setting name="CoveFsLogSizeMB" serializeAs="String">

In this case the name is CoveFsLogSizeMB.

There are also numerical values and time values.

Settings

Settings are organized by function.

Obsolete settings are crossed out.

  • Smtp_UseSsl - When set to True a SSL connection will be established with the SMTP server.

Remove Drive

  • RemoveDrive_PoolReadOnly - Make unduplicated folders on the pool read-only while a disk is being removed. Duplicated folders are always made read-only to preserve data integrity.


Don't forget to rename the config file after you make the change and restart the server (or service), as noted at the top of this page.

RemoteControl.xml

Allows you to configure some of the settings for the Remote Control features of the DrivePool 2.x User Interface.

The file is located in C:\Program Files\StableBit\DrivePool\RemoteControl.default.xml on the server.

In order to put the file into effect, you will need to rename it to RemoteControl.xml and restart the server (or just restart the StableBit DrivePool system service).

Any time you upgrade, or reinstall DrivePool, it writes an updated RemoteControl.default.xml file, so it will include any updated settings but leaves the current RemoteControl.xml alone so it doesn't alter any of your settings.

MulticastDiscovery

This setting is configured to be "enabled" by default, so that the User Interface will automatically find clients. However, you can set the value to "False" and this will only list entries that you have manually added to the "Peer" list.

The setting should look like this:

<MulticastDiscovery Enabled="True" />

Peers

The Peers Section allows you to specify a list of computers that you want available, in cases such as a specific computer isn't picked up by the automatic discovery, or if you want to disable automatic discovery and manually list the computers available.

All clients must be running the same version of DrivePool, and you must have any additional balancer Plugins installed as well.

Peer

You need to manually create an entry for each computer to be added. You can use the computer's host/DNS name, or the IP address, and you can specify a different port (if the service is configured for that, see Control above).
