cluster performance degradation
- Thread starter toto-ets
- Start date
The problem arose in mirror-0, look at post #130: one device is REMOVED and the other one has 138/244 read/write errors.
And - of course - only one device is allowed to fail in a mirror. The moment the survivor delivered errors the pool stopped working --> suspended for maintenance...
For sure the timing - the sequence of events - is important, but this is my impression.
In the same #130 your wrote:
It is not a good idea to remove one twin while the other part of the mirror has reportedly errors. A scrub would have possibly repaired that. To scrub later on will leave damaged data in some files ( with a high probability) - but the pool in itself should be usable again.
I added the third node, now I will do all the other tests, but now I have this problem, I can't delete this HA, it gives me this error, I don't see it configured in the VM, what command do I have to send to delete it

I do not know - it seems you are drifting further into problematic areas while pve1 is still missing.
Fortunately "Quorum: OK" is stated --> "/etc/pve" should be writable. So if you want to work below the official surface: take a look into
/etc/pve/ha/resources.cfg. If you are brave you may edit that file (make a backup-copy first!) and remove the probably present "vm: 101" stanza completely. This manual and for sure unsupported direct manipulation should be visible in the WebGui after a very few seconds.Good luck.
look now, pve1 active, and vm on pve 1, same error, and as if the vm does not exist, but in reality it is there..
In that list you see just the available vm/lxc which could be given a resource !!
So it's normal that you cannot remove it as for this vm no ha is defined yet
if I try to create it it gives me this
