Re: Instance filesystem corrupt

[<Keynes_Lee@xxxxxxxxxxx>]

 

Hum ~~~seems we have in common

We use

rbd snap create to make snapshot for instances volumes

rbd export and rbd export-diff command to make daily backup.

 

Now we got 29 instances and 33 volumes

Actually i have the same problem when starting an instance backed up by librbd

But this only happens when trying to start 60+ instance

 

But I decided that this is due to the fact that we are using old hardware that is not able to respond to high demand.

 

Could that be the same issue that you are facing ?

I am not aware of any similar reports against librbd on Firefly. Do you use any configuration overrides? Does the filesystem corruption appears while the instances are running or only after a shutdown / restart of the instance?

No , we are using Firefly (0.80.7).

As we are using HPE Helion OpenStack 2.1.5, and what the version is was embedded is Firefly.

 

An upgrade was planning, but should will not happen  soon.

Just out of curiosity, did you recently upgrade to Jewel?

We are using OpenStack + Ceph.

Recently we found a lot of filesystem corrupt incident on instances.

Some of them are correctable, fixed by fsck, but the others have no luck, just corrupt and can never start up again.

 

We found this issue on vary operation systems of instances. They are

Redhat4 / CentOS 7 / Windows 2012

 

Could someone please advise us some troubleshooting direction ?
