Disc Unmountable: Wrong or no file system

[slobert]

I have a disk on the array that is unmountable and has read errors. Is it toast?

Version: 6.11.3

 

xfs repair status:

Phase 1 - find and verify superblock... superblock read failed, offset 0, size 524288, ag 0, rval -1 fatal error -- Input/output error

 

recent disk log entries in the red:

Disk does appear to be failing, xfs_repair cannot repair a disk that returns a read error, hence the input/output error, since there's no parity best bet is to clone it with ddrescue then run xfs_repair.

Thanks for the tip. I've got some drives on the way. I'll clone it and set up parity.
