    Snapshot removal fails after backup

    Okay, that's a different story... Sounds good in any case. Guess this gives me enough to advocate upgrading. Thanks!

    Snapshot removal fails after backup

    Yes we do, still on 1.7. We want to have enough confidence that it's really solved before upgrading, because testing and upgrading also takes a lot of preparation and additional downtime. nc1-node2:~# pveversion -v pve-manager: 1.7-10 (pve-manager/1.7/5323) running kernel: 2.6.32-4-pve...

    Snapshot removal fails after backup

    I'm afraid that's probably a different issue being solved in bug 127. In the case of the crash, the lvremove command doesn't even terminate, so there's no chance of executing the second lvremove. The lvremove command hanging and causing the kernel crash is the real problem here; the snapshot not...

    Snapshot removal fails after backup

    We have the exact same problem, running LVM on top of an Intel Modular Server's shared LUN (shared across 3 nodes) using Proxmox 1.7 (KVM only). Sometimes it doesn't happen for months, but now it happened yesterday AND today. That would be about the 9th time in 10 months. It's becoming a real...

    Proxmox VE 2.1 released!

    Looks promising! Do you happen to have a reference to back up this statement (e.g. specific LVM bug fixed)? Thanks, David

    i/o problem

    Well, I can confirm: also with non-overlapping backup windows I got the crash last night...

    i/o problem

    Good point. On second thought, my nodes do share the same I/O controllers (Intel Modular Server), so overlapping backup windows can also create higher I/O than normal. If it's not a concurrency issue, it can still be a load issue. In any case, I'll make sure the backup windows don't overlap, it...

    i/o problem

    Currently I'm thinking it might have something to do with the fact that my VMs are on a shared LVM volume group (shared across cluster nodes), and that one node starts the backups while the other hasn't finished yet. Is that somehting that may happen in your environment as well?

    single host, many drives, advice..?

    I believe that's not the case. The installer might use all drives as physical volumes for one large volume group it will create. I recommend removing the 4 drives, installing proxmox, adding the 4 drives again, and then assigning these as storage for VMs.

    i/o problem

    So, after the intial tests... was this the solution? (Judging by more recent posts it seems that this didn't help either?) Thanks, David

    A potential LSI fix?

    Hi Rob, Our servers are also suffering from the LSI related LVM snapshot problem, so I'm following up on any solutions... However, the articlae you refer to is about MegaCli in combination with SATA disks. We're not using MegaCli, and we're also not using SATA disks (although maybe you are?)...

    single host, many drives, advice..?

    I think the RAM is very important here. If all your VM's need 1 GB RAM, they will (almost) fit in the 8 GB you have. Whether the HDDs or the NICs will be a bottleneck will depend on the load I would say.

    Feature request: select which disks are backed up

    Alternatively (maybe easier to implement), another solution may be to make it possible to specify a maximum size of the disk to be backed up. This way you can omit larger disks from the backups.

    Feature request: select which disks are backed up

    Mike -- while waiting for this feature, have you implemented a workaround? Thanks, David
