Eh, OK. Thx for the info. BTW why is 16 snapshot limits hardcoded - any reason for that ?
Not cleaning snapshots on CEPH and trying to delete volume after having more than 16 snapshtos in CEPH = Agent crashing on KVM side...and some VMs being rebooted etc - which means downtime :| Thanks, On 9 September 2015 at 22:05, Simon Weller <swel...@ena.com> wrote: > Andrija, > > The Ceph snapshot deletion is not currently implemented. > > See: https://issues.apache.org/jira/browse/CLOUDSTACK-8302 > > - Si > > ________________________________________ > From: Andrija Panic <andrija.pa...@gmail.com> > Sent: Wednesday, September 9, 2015 3:03 PM > To: dev@cloudstack.apache.org; us...@cloudstack.apache.org > Subject: ACS 4.5 - volume snapshots NOT removed from CEPH (only from > Secondaryt NFS and DB) > > Hi folks, > > we enounter issue in ACS 4.5.1 (perhaps other versions also affected) - > when we delete some snapshot (volume snapshot) in ACS, ACS marks it as > deleted in DB, deletes from NFS Secondary Storage but fails to delete > snapshot on CEPH primary storage (doesn even try to delete it AFAIK) > > So we end up having 5 live snapshots in DB (just example) but actually in > CEPH there are more than i.e. 16 snapshots. > > More of the issue, when ACS agent tries to obtain list of snapshots from > CEPH for some volume or so - if number of snapshots is over 16, it raises > exception (and perhaps this is the reason Agent crashed for us - need to > check with my colegues who are investigatin this in details).
