Hi,

Pangolin occured issue today around 1:00 PM, 503 service unavailable for hg.slitaz.org / forum.slitaz.org.
Suspect issue on private service provider between DC, but other traffic work for mirror and tank.

Connect on kvm to first node who host pangolin, and discover boot stuck on grub.
Reboot it to live cdrom, can't mount filesystem.

Need investigate what happen, infact hypervisor system are good, filesystem also, on same hypervisor we have mirror that no issue occured.

I restore backup daily doing this day midnight on second hypervisor.
second partition seem no impacted, i restore mysql database from datas before crash.

Sorry for apology :/

Hi,

After more investigations, think found cause but need to plan intervention :
mirror zfs state HEALTHY
SMART test on disks PASSED fort both disk

But for second disk see have 580 reallocated_sector, 0 current_pending_sector, 0 udma_crc.

In case i nothing receive because all return good state :/

At time pangolin run on other node, remain mirror vm on it, check to move on another node to avoid break this.

Hi,

Disk replaced, check it's ok for SMART and sector reallocated value.
- ZFS resilvered for system / vm_data mirror partitions
- EFI partitions synced
We are come back to safe state.

VMs come back to original node.
