Hello,
I had an OSD drop out a couple days ago. This is 14.2.16, Bluestore, HDD +
NVMe, non-container. The HDD sort of went away. I powered down the node,
reseated the drive, and it came back. However, the OSD won't start.
Systemctl --failed shows that the lvm2 pvscan failed, preventing the OSD
unit from starting.
Running the pvscan activate command manually with with verbose gave
'device-mapper: reload ioctl on (253:7) failed: Read-only file system'. I
have been looking at this for a while, but I can't figure out what is
read-only that is causing the problem. The full output of the pvscan is:
# pvscan --cache --activate ay --verbose '8:48'
pvscan devices on command line.
