Hi, I just upgrade my proxmox server to a new hardware IBM x3650-M5, I used same proxmox boot disk from the old system (older hardware, so it was boot from grub). I have to use legacy bio boot in order to be able to boot from the disk. Here is output for "proxmox-boot-tool status"...

Hi, I have a PBS setup and running just fine, but yesterday I had a disk failed, but realized I do not know how to find that which slot is my failed disk to be replaced. The failed disk shown as sdh (which is the last disk in GUI screen), so I assume that is the last disk #4 (I only have 4...

Hi, I have 8 nodes HA system, ceph running on 6 nodes with 12 osd. Once a week, I will see a spike in OSD apply & commit latency max reading (see attached picture), wondering how to trouble shoot it, which node and which osd causing this? Any help would be much appreciated.

Great, very helpful. thank you.

Hi, As per attached zpool status -v output, I have few questions on how to setup a mirrored special device for pool name "Charlie-Backup", here what I did: 1. original, I was able to setup a mirror-1 special device by sdd and sde (both are ssd). 2. then I want to change sdx to disk-id...

Hey; Thanks for your reply. I am not sure. I had a old pool with spin disks, and I just added a ssd as an special device into the pool, and want to rewrite the whole pool (existing pool) so my special device can take effect.

Hi, Johannes; Thanks for your reply. Here is my code, please double check whether It will work or not, I have two zfs pool, data1 (which I want to snapshot and rewritten the same pool), rpool (which has proxmox on it). and data1 has enough space for a duplicated copy. zfs snapshot...

Hi, I setup a new ssd as a special device to my backup server storage pool, and I had some old backup on the storage pool (all spin disks before), how to rewrite these old backup and so new meta data can be written onto that ssd special device? thanks in advance.

Also, after I add a special device, exactly how to use zfs send/receive to gain the speed of my old backup? originally I thought to delete the old backup, and start a new one. Now I am wondering whether there is a quicker way to handle all my old backup at once.

Great stuff, thank you very much.

Hi, I want to speed up GC process by adding some ssd to backup server, I read some of threads here, my understanding is, I could use ssd for some files that GC process would need to access.

Woo, very detailed. Thank you. Just want to clarify one thing, I still want to keep my sas disk drives for all actual data backup, and these ssd only for necessary indexing data (I called mega data), so I can speed up GC process. I have about 60Gb stuff to backup, I was planning to use 1tb ssd...

Hi, I had a pbs running with 4 sas disk drives, and GC takes 7 days to complete. After some reading, I think to setup a new ssd storge and use it for all mega data, that would speed up GC process. move backup mega data to ssd, so GC will be faster. Anybody could suggest how to move mega data...

Hi, Currently I am running Proxmox 7 on 5 node cluster, I have E5-2643 V2 for cpus, wondering can I safely upgrade to proxmox 8 on my machines? I am thinking to upgrade my machines in 3 years (will have E5 V3 cpus), do you think I can keep my old cpus for at least 3 years? Thanks.

I think I found my answer. In gui / osd page, I discovered two osds has longest latency, replaced those two disks, then it seems very thing is good now.

Hi, I have 8 nodes HA system, ceph running on 6 nodes with 12 osd. Once a week, I will see a spike in OSD apply latency max reading (see attached picture), wondering how to trouble shoot it, which node and which osd causing this? Any help would be much appreciated.

Great, I will look into that. It seems verything is ok now, I will note this down, and see whether it will repeat itself. thanks

Hi, I have a 6 nodes proxmox HA setup, and with ceph running / 18 ssd osds. I get following warning often, not sure how to trouble shoot, possible: 1. which osd causing this warning? 2. which node causing this warning? 3. this warning is due to ssd disk? or could be something to do with...

great, I got it done. thank you very much.

Hi, I installed a new sas 12tb disk, but I can not get it initialized, give me error and task fail. I used smartctl -i /dev/sdx to check it and compare the result with a existing and working disk, I found the new disk was formated with type 2 protection, but my old working disk does not. I...
