Hi All,
we are backuping date to prod flex appliance and replicating them to DR flex appliance using SLP
we need to reclaim space on DR site, so we have changed the retention on DR and expired all not needed images by right click on each image on the catalog (java console) and click on expire
now after 3 days , no changes on the space of the msdp pool, still same size before expiration.
any help please to reclaim space
If you have IT Analytics running you can create a report to see what backup images had the largest amount of unique data ingested into your disk pool ie. poor dedupe clients. Those will be your best chance to reclaim space. You are probably just expiring images that really had no unique data and dont reclaim much if any space.
The command "crcontrol --queueinfo" will give you the number of cleanable blocks. If the number is small, then there is nothing to clean. It must be more than 7 or 8 digits to get some space.
Unfortunately, this is how deduplication works. If the deduplication ratio is high, then less space is reclaimed after a backup deletion.
Imagine that you are backing up a shutdown VM. After the first backup, the deduplication is 100%. The same applies for the next backups. So after 100 backups of the same system, if you delete 90 backups, the space you reclaim will be 0.
If you expect more free space after the image deletion and the MSDP cleanup, I suggest opening a case to investigate. However, my experience indicates that there is likely no cleanable space.
thank you for the answer.
crcontrol --queueinfo gives the number 66 197 296
just a question, it is not related to the original backup (first copy done in the prod site before replication with SLP) , i'm thinking on dependencies as before expiring the retention setting of replicated copy was the same as the backup.
the replicated image in the DR which is expired, maybe is waiting the 1st copy in the prod to be expired also, i am not sure.
first restart the DR master server services. Some times the cleanup processes stack and does not work.
Then run
on the master server
nbdelete -allvolumes
bpimage -cleanup -allclients (check the activity monitor the cleanup progress and then run the next command)
bptm -delete_expired
on the msdp server
crcontrol --processqueueinfo (note the busy and the pending )
Run two times the "crcontrol --processqueue"
after that both busy and pending will be "YES"., Wait until both are "NO"
Hi StefanosM​
Thank you for the clear answer.
all steps are done, now busy and pending are NO but no space are reclaimed, the situation is still the same
