Disk Images

Advanced disk has been superseded by the disk deduplication solutions on offer now with integration into NBU via OST. The advanced disks relevant commands are listed here for completeness.

 

To check the images on a AdvancedDisk volume use the following :

# bpstsinfo -imageinfo -servername <storage_server> -stype AdvancedDisk -lsuname /path/to/filesystem

To check which images are on a puredisk volume use the following :

# bpstsinfo -imageinfo -storage_server  <storage_server> -stype PureDisk -media_id

@<media_id>

As an example to compare what is known within the EMM And what is known on the disk pool, run the following for an advanceddisk pool :

# bpstsinfo -comparedbandstu - storage_server <storage_server> -stype AdvancedDisk

-lsuname /advanceddisk/dp1/advol -media_id @aaaac

To compare what is known within the EMM And what is known on the disk pool, run the following for a puredisk pool : 

# bpstsinfo -comparedbandstu -storage_server <storage_server> -stype PureDisk

-lsuname /msdp/data/dp1/pdvol -media_id @aaaaf

To delete an image  a Puredisk volume:

# bpstsinfo -deleteimage -servername <storage_server> -stype PureDisk -lsuname 

PureDiskVolume -imagename <hostname>_1507195382_C1_IM -imagedate 1507195382

If there are fragments to be deleted in the image deletion table but the disk storage / volume on which they resided has been decommissioned then the deletion list needs to be purged otherwise the image clean-up will exit with a status of 1. To purge the image deletion table run the following command for the relevant media id of the decommissioned volume.

# nbdelete -purge_Deletion_list -media_id @<media_id> -force

Also remove any locks for the relevant media id from the /usr/openv/var/nbdelete directory

Once the above steps have been completed rerun the image cleanup
