Not long after writing the last blog the M.2(in a SATA conversion case) in my Lenovo M700 Tiny failed. After doing some detective work I resolved to work on getting the CEPH cluster back up and healthy. Listed below are the steps taken to get things back up and running.
- Migrate VMs/CTs to an unaffected node to minimize drag on those VMs
- Pluged in a spare USB Flash Drive(if possible matching the size of the failed drive)
- Add as OSD in Proxmox CEPH GUI(this was a stop-gap till replacement acquired)
- Purchased new 500GB NVME and NVME-to-USB adapter
- Connect the new drive in the adapter and add it as an OSD to CEPH through Proxmox GUI
- Remove flash drive as OSD from CEPH through Prommox GUI
Clear CEPH alerts/warnings using this CLI command
ceph crash archive-all
- Restart CEPH Manager
After recovering some house cleaning was in order, added a few machines to the HA that needed it. Fingers crossed so far all is well, but I plan on upgrading all the drives to match with new hardware over time and dedicate a node or two just to CEPH, but that’s for a later date.
Fair winds and following seas.
