Hi,
I have a node on a HP elitedesk 800 G2 sff, with a Lexar NQ710 nvme M.2 disk, ZFS.
When I stress the disk (local backup for example, but also some operations inside a 150MB VM), it spikes IO delay and disk temp until it loses temporally the connection with the nvme, then it gets back to work as soon as I stop the workload:
It works flawlessly if I do the backup to an external NFS storage, or through PBS.
Is there a way to better understand where the problem is?
- incompatible nvme to the (old) mainboard
- faulty (old) mainboard/linux driver
- faulty (quite new even if not much performative) nvme
I do not see that much thing from the syslog or anywhere else during the spikes, only the system going down and back up when it loses disk control:
I know I can update the BIOS but would know if there's something else I can do to debug and plan a solution.
Thank you.
