CBT: the thread to centralize your feedback

@flakpyro did the same test with nfs based vm, but also can’t reproduce the problem here.
-
@olivierlambert unfortunatly it did not resolve the stream problem, just got another one.
-
@olivierlambert I just got this error to on our production pools!

@julien-f and the stream error?
-
@rtjdamen We are investigating it as well
For the XO backend team, the next few months are focused on stabilization, bug fixes and maintenance

@julien-f @florent @olivierlambert I'm using XO source master (commit c5f6b). Running Continuous Replication with NBD+CBT and Purge Snapshot. With a single (one) NBD connection on the backup job, things work correctly. With two NBD connections I see some Orphan VDIs left almost every time after the backup job runs. They are different ones each time.
-
I noticed when migrating some VDIs with CBT enabled from one NFS SR another that the CBT only snapshots are left behind. Perhaps this is why a full backup seems to be required after a storage migration?
-
@flakpyro i know from our other backup software we use that migrating cbt enabled vdi’s is not supported on xen, when u migrate between sr it will disable cbt on that vdi. This is causing a new full. This is by design
-
@rtjdamen Makes sense, it would be nice is XOA cleaned up these small CBT snapshots though after a migration from one SR to another.
-
@flakpyro indeed, sounds like a bug. It should delete the snapshot, disable cbt and then migrate to the other sr.
-
I've been out of life for a while.
is it any known problem with CBT file restore?
-
@Tristis-Oris Working fine here, with cbt backups.
-
@Tristis-Oris Is your backed up VM using LVM for it's root filesystem?
-
@Andrew most of them, yes.
-
@Tristis-Oris This is a known issue from before and not related to CBT backups.
