What happened?

We have a ETCD cluster of kubernetes which has one member with ETCD version - 3.5.3 and it was up and running from a long time of 25 days. Suddendly something happended in ETCD and getting restarted frequently,ETCD is throwing the error below as "panic: failed to recover v3 backend from snapshot"

"message" : "panic: failed to recover v3 backend from snapshot"

What did you expect to happen?

There should not be any issue in ETCD service and ETCD should be up and running instead of complaining about the missing snapshot file.
Is there any specific reason due to that ETCD had missed the snapshot file , Could you please help us to find the root cause of the issue ?

How can we reproduce it (as minimally and precisely as possible)?

We don't know the steps to reproduce it as it is not reproducible.

Anything else we need to know?

Looks like a duplicate of #14382
Please upgrade to v3.5.5

cc @ahrtr Looks like fix for #14382 is not mentioned in v3.5.5 changelog or I missed it?

ETCD_QUOTA_BACKEND_BYTES: 268435456

Why do you configure such a small value (about 268MB) ? Please check the db size. I suspect it ran out of the quota. If yes, then most likely the same issue as #14382.

It's included in the 3.5.5 changelog. Fix [etcd fails to start after performing alarm list operation and then power off/on]

Thanks for confirming. I must have searched it incorrectly.
Closing the issue as it was already fixed in the newest release.

Hi @ahrtr
is the panic error 'failed to find database snapshot file' in the etcd log due to insufficient db size ?
The ticket #14382 is indicating that a hard reboot happened on underlying worker nodes and due to this reboot ETCD service went down.
Could you please help to understand the root cause of this panic error ? This panic message issue is due to insufficient db size or due to hard reboot ?

Thanks,
Satya
