VictorSTS replied to the thread backup stop mode doesn't stop the VM.You need to understand how backup works. Specifically in stop mode: VM is running PVE tries to do a shutdown of the VM: If QEMU Agent is configured and running, shutdown signal is issued with it. Else, sends an ACPI signal which guest OS may or... -
VictorSTS replied to the thread PBS Verify duration on large HDD-based datastore — how to tune settings?.I mean a "RAID0 of two RAIDz2 vdevs". Something like this: zpool create tank \ raidz2 disk1 disk2 disk3 disk4 disk5 disk6 disk7 \ raidz2 disk8 disk9 disk10 disk11 disk12 disk13 disk14 That's true, as I mentioned above: That happens...

VictorSTS replied to the thread PBS Verify duration on large HDD-based datastore — how to tune settings?.Good point!! I did assume OP had at least a mirror of NVMe for special device. Should be a mirror of 3 to give it the same redundancy as the HDD part. None of those settings will really help to increase performance on your big zpool on verify...

VictorSTS replied to the thread PBS Verify duration on large HDD-based datastore — how to tune settings?.Find out yourself with your hardware: apt install sysstat Start two terminals: iostat -dx 2 top -H Increase readers until the load on iostat for every disk is ~90% (or some lower limit to leave headroom for other activities on the same zpool)...

VictorSTS replied to the thread Proxmox update from 8.4 to 9.You must upgrade first to latest 8.4 (think it's 8.14.17 at time of writing) and Ceph 19.2.3 (Ceph Reef isn't supported in PVE9). It's clearly stated in the upgrade docs [1]. The Ceph upgrade docs are here [2]. Once you are in latest 8.4.x, and...

VictorSTS replied to the thread Ceph rbd du shows usage 2-4x higher than inside VM.Yes, can be run on a live VM in the sense that the command runs, i.e. doesn't check if the given rbd image as an owner/lock, so we can suppose it's safe. As you mention, Ceph docs doesn't explicitly tell if it can be run live or not. That said, I...

VictorSTS replied to the thread Ceph rbd du shows usage 2-4x higher than inside VM.Problem could be that your "trim" stopped working at some point for some reason (i.e. discard wasn't ticked in the VMs disk configuration) and even if fstrim tries to discard the whole free space, the underlying storage stack will only act on...

VictorSTS replied to the thread PVE 9.1.1 Memory bug ? + Windows Server 2025 installation experience sharing.For Windows to properly report used memory to PVE you need: - Virtio Balloon driver and service installed and running (installed and enabled automatically with the VirtIO ISO installer). Don't confuse this with QEMU Agent, which does different...

VictorSTS replied to the thread Hook script not executed on source host of migrating VM.IIRC, unfortunately pre/post migration hook scripts aren't implemented yet [1]. The source PVE will have no clue the VM is no longer running in it. [1] https://bugzilla.proxmox.com/show_bug.cgi?id=1996

VictorSTS reacted to bbgeek17's post in the thread Storage for small clusters, any good solutions? with
Like.
Hi @RoxyProxy, Since questions around pricing, company future, and so on came up, we felt it was appropriate to chime in. First, we'd like to thank the Blockbridge customers earlier in the thread for sharing their thoughts. To be honest... -
VictorSTS reacted to Onslow's post in the thread [SOLVED] No zfstools in the latest kernel 6.17.9-1-pve with Like.
At https://packages.debian.org/forky/amd64/zfsutils-linux/filelist I can see there are /usr/bin/zarcstat and /usr/bin/zarcsummary Maybe those were renamed in the newer version? What about man zarcstat ? P.S. Indeed...

VictorSTS replied to the thread Ceph squid OSD crash related to RocksDB ceph_assert(cut_off == p->length).Thanks for the heads up. Pretty sure most where created with Ceph Reef except a few that got recreated recently with Squid 19.2.3. I'm aware of that bug, but given that I don't use EC pools (Ceph bugreport mentions it seems to only happen on OSD...

VictorSTS reacted to fstrankowski's post in the thread Ceph squid OSD crash related to RocksDB ceph_assert(cut_off == p->length) with Like.
Best of luck to you * fingers crossed *. I had to rebuild the whole cluster in my clients case and fix ceph by manually restoring placement groups - which was a pain.
-
VictorSTS replied to the thread Ceph squid OSD crash related to RocksDB ceph_assert(cut_off == p->length).@fstrankowski I'm fully aware about the risks of OSD being full and know how to deal with that, but in any case an OSD should break because of that ;) Definitely fragmentation has an impact on this and will watch it more closely from now on...

VictorSTS reacted to fstrankowski's post in the thread Ceph squid OSD crash related to RocksDB ceph_assert(cut_off == p->length) with Like.
Initially i'd like to raise concerns about the amount of available storage already beeing in use. By default CEPH doesnt allow more then 80% so you'd have to take precautions really soon while taking these concerns into consideration. I'd highly...

VictorSTS replied to the thread Ceph squid OSD crash related to RocksDB ceph_assert(cut_off == p->length).In short: if Ceph warns you about something, do something about it. Read the full bugreport and found this comment [1]: "This issue seems to mostly affect disks which were heavily fragmented.". Mine are and in fact I have some warnings related...

VictorSTS posted the thread Ceph squid OSD crash related to RocksDB ceph_assert(cut_off == p->length) in Proxmox VE: Installation and configuration.PVE8.4.14 + Ceph 19.2.3, 3 node cluster. All disks are PCIe NVMe. Different pools, some with zstd compression enabled. I'm seeing OSD crashing lately with the same failure. Journal shows that it is unable to properly run RocksDB with an assert...

VictorSTS reacted to Zappes's post in the thread I want nothing more than encrypted push sync with Like.
Sure, no problem: https://bugzilla.proxmox.com/show_bug.cgi?id=7251

VictorSTS replied to the thread I want nothing more than encrypted push sync.@Zappes please, link the Bugzilla you mention here [1]. I would love to be able pull (not push) encrypted syncs where the source is unencrypted for any reason and destination PBS must store encrypted backups. [1]...
