We have suffered some server Failure but when the server came back ceph had to restore\rebalance around 10-30TB of data, Ssds are based on relativly high end sas ssds (4TB segate nitro and hp\dell 8TB pm1643 based) Network is 2x40Gb Ethernet (one dedicated for sync\replication and one for...

i found a workaround: after i receive the error of rpool not found. i should wait around 1-2 minutes at least and then run zpool import -N rpool -f after it worked i changed the zfs sleep time and now it more stable

anyone got another idea? i am not willing to reinstall the server. i tired to recover the boot via installation cd but it failed

give the error: cannot import 'rpool': no such pool available

How i can get to a menu to update zfs sleep args? "ZFS_INITRD_PRE_MOUNTROOT_SLEEP"

for some reason i thought it worked. and tried to do another reboot, now after running zpool import i receive no pools available

grub files does not exist, i updated zfs pre sleep, but how i "commit" force config update for the change? because update-initramfs does not exist

how i can scann the boot drives?

*yes from iso zpool import: lbsk: ls -la /dev: starts with blkid: the end of dmseg:

This morning we had some power outage issue on our server room, all nodes recovered except one. This node is part of (one of three) ceph cluster , (pools are set to replication 3) so the data is safe and the cluster is stable, (excluding ceph warning) Any idea how i can fix it?

the proxmox host had the same ram usage as before: the max ram available to the vm was marked as used, even when the vm used around 1% of the ram

i installed virtio and enable the flag, but the system still uses all ram and it is not shared i see "BalloonService " running on windows

I assume that this is impossible, but ill ask this anyway. i need to put one lxc (ubuntu) and one vm on each host (for large computational tasks) somtiems we need windows and sometimes we need linux the problem that the VM need to have all the ram prealocation and not freed when not in use...

nfs (qnap based) over 40GB network. tmp dir is default (what come pre configured with proxmox)

i have lxc containers hostes on ceph storage (with speed over 5GBs ) when making backup using zstd the speed is between 20-90MBs the storage i am writing to store the backup have read/write speed around 1GB proxmox 6.2.12

my mistake, repository was on strech insted of buster . updating .. upgrade fixes the issue, thanks

most nodes are 6.2-11 (oldest is 6.1-2) (upgraded but did not rebooted yet)

on some hosts the ZSTD backup compression is not working? any idea why ? this is the error? Parameter verification failed. (400) compress: value 'zstd' does not have a value in the enumeration '0, 1, gzip, lzo' solution: upgrade proxmox to latest version on all nodes.
