XCP-NG 8.3 freezes and / or reboot on HGR-SAP3 by Ovh / Using ZFS on Raid 50 / With deduplication
-
Probably worth trying regular local ext SRs (in mdadm if needed) and see how it behave. KISS principle is very strong in general.
-
Unfortunatly this is also my conclusion.
This is what I used to do with smaller servers.
This is the first time with such a "huge server" + hardware RAID + ZFS with dedup.Thanks
Have a nice day -
It will be a lot better with future SMAPIv3 drivers (it might include ZFS if we want to officially support it)
-
Do you think the problem could be due to ZFS deduplication ?
I just saw that it's possible to disable deduplication "without restarting" .
I think my problem is due to excessive disk writes (adding then deleting a snapshot, then coalescing?)
Without deduplication, less disk usage ?Or am I wrong ?
-
In general, at least the consensus, is to NOT use deduplication with ZFS. It's probably one cause of the issue, yes. It's not worth the RAM needed.
-
Yes, I should probably create a new post ?
To discuss and "to survive" : how to make my current server usable again- starting by testing with deduplication turned off.

Let's continue there, you can always rename your thread

Okay, but I can't edit the subject.

You can edit your first post, which contains the title

thanks a lot
I'll wait until next week to disable deduplication (never on Friday
)
