QJournalDir The location where the queue is stored.
Values: any valid path
Default: the location specified during the installation
For best results and reliability, you should select a dedicated, non-boot volume. The queue should
be stored on a fixed, local NTFS volume.
This location also stores the Storage Mirroring driver pagefile.
QJournalFileSize The size, in MB, of each queuing transaction log file.
Values: any valid file size, up to 4095 MB
Default: 5
QJournalFreeSpace
Min
The minimum amount of disk space, in MB, in the specified
QJournalDir that must be available
at all times.
Values: dependent on the amount of physical disk space available
Default: 50
The QJournalFreeSpaceMin should be less than the amount of physical disk space minus
QJournalSpaceMax.
QJournalPreload The number of operations being pulled from the disk queue at one time. Do not modify this
setting.
QJournalSpaceMax The maximum amount of disk space, in MB, in the specified
QJournalDir that can be used for
Storage Mirroring queuing. When this limit is reached, Storage Mirroring will automatically begin
the auto-disconnect process.
Values: dependent on the amount of physical disk space available
Default: Unlimited (equivalent to 4,294,967,295 MB)
The unlimited setting allows the disk queue usage to automatically expand whenever the available
disk space expands. Setting this option to zero (
0) disables disk queuing.

disk.
