Hello Guys! I'm setting up our new cluster at the moment. The cluster network is a 25 GBit Full-Mesh configuration between the nodes (up and running! ;-) ) To follow the KISS principle and reduce the point(s) of failure I thougt about a second mesh for corosync (with fallback over public...

Hello guys. I plan to change the harddisks of the B2D-Storage in our BackupExec VM. Recently this is a zfs-mirror configured on the pve host which is connected to the vm via a virtio block device because of problems with the virtio scsi driver at installation time. (see...

Hello. I have a running VM on ProxVE 8 with 3 disks on 3 different storages. They all have the same (file-) name. That makes it a bit confusing if you check the content: Second problem: There is no "notes" field or similar that shows the name of the corresponding VM. This could be a...

It seems to work... till now... ;-) Thank you for your help!

I followed the guide und added the following line (24GB) cat /etc/modprobe.d/zfs.conf options zfs zfs_arc_max=25769803776 The result is an entry (after reboot and "update-initramfs -u -k all") in: cat /sys/module/zfs/parameters/zfs_arc_max 25769803776 The UI shows: Actually the ram usage...

Thanks. I've overlooked that... ;-)

How do I limit the size of memory for zfs, e.q 24GB ?

Is there no control function to lower the memory usage of zfs if there are other processes which need memory?

Hello! We bought a new backup server last year. The file system is ZFS. The memory usage is always high, which seems to be normal with zfs. The server has 64GB RAM and there is one virtual machine with 16GB RAM (Windows Server 2019). So after one day (since a reboot) the memory usage of...

Shutting down the vm, does the trick! Thank you... But I saw krbd isn't active on our ceph storage. Can it be activated without risk?

Just to be sure (and have someone else to blame ;-) ) This is one of the VM's with snapshots I tried to remove by GUI - which ends in an error (and a locked snapshot): I don't remember (maybe it wasn't me?) but as you can see there are changes made to the harddisk (size). Is this the cause for...

The output of "rbd -p <pool> ls -l" shows all disks of the cluster, right? That means the output is (should be) the same on all cluster-nodes?!

I got the same problem as the tread-starter: I changed the disk from ide to virtio (with snapshots taken before) und after the conversion I'm unable to delete the snapshots in the gui ("disk ide0 not found" or something like that). How can I check if there are any snapshots on disk (ceph...

Hello Guys. Time to dig out an old thread... :cool: What I do not understand is how snapshots are consolidated if I manually delete them from the config file... I'm coming from Hyper-V and there is the oldest disk the "mother" of all. So if I delete any differencing disk between the first...

How can I find out then if the limit is set too low?

it's oob... what's a rational limit?
