Fwd: [ceph-users] [IMPORTANT NOTICE] Potential data corruption in Pacific

[Eneko Lacunza]

Hi,

Regarding this important issue reported for Ceph (just cross-forwarding 
for those Ceph users not in ceph-user list):

1. Proxmox upgrade wiki page 
https://pve.proxmox.com/wiki/Ceph_Octopus_to_Pacific marks as optional 
disabling the conversion with "ceph config set osd 
bluestore_fsck_quick_fix_on_mount false", and urges to convert ASAP. It 
is now advised not to perform the conversion until a fix is released.

2. We have upgraded 2 clusters, but both have 
bluestore_fsck_quick_fix_on_mount set to false. No command setting that 
flag in our server's history, so I don't think we set that (I wasn't the 
admin performin the upgrade, I'll be able to check with her tomorrow)

3. Is it possible that for ceph 16.2.6 bluestore_fsck_quick_fix_on_mount 
default value is false?

I expect an emergency fix released soon but I guess checking won't hurt 
anyone ;)

Thanks
Eneko
