I recently added some storage to a RAID array with a single large XFS volume. To expand the volume I normally use parted to remove the partition and then recreate it so that it spans the entire volume.
However, I accidentally removed a partition from /dev/sdb1 instead of /dev/sdb, and cannot seem to restore the partition.
BEFORE:
/dev/sdb looked something like:
(parted) unit s (parted) print Model: xxx Disk /dev/sdb: 58589705392s Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 2048s 58589705358s 58589703311s xfs data
and,
/dev/sdb1 looked something like:
(parted) unit s (parted) print Model: Unknown (unknown) Disk /dev/sdb1: 58589705392s Sector size (logical/physical): 512B/512B Partition Table: loop
Number Start End Size File system Flags 1
0s 58589705392s 58589705392s xfs
(sizes might be a little bit off, but other flags like the partition type and filesystem type are accurate)
AFTER
After accidentally removing the partition in /dev/sdb1, I tried first recreating it in /dev/sdb1 with no luck, then I tried creating the partition in /dev/sdb using "mkpart primary xfs 2048s -1s", but the filesystem does not show up:
/dev/sdb now looks like:
(parted) unit s (parted) xxx /dev/sdb: 58589705392s Sector size (logical/physical): 512B/512B Partition Table: gpt
Number Start End Size File system Name Flags 1 2048s 58589705358s 58589703311s primary
when I try running parted /dev/sdb1 and looking at things there I get:
(parted) print Error: /dev/sdb1: unrecognised disk label
I've tried removing and recreating the partitions in a few different ways, but so far have not been able to restore the original XFS partition so that I can grow it
Any suggestions?
Any help would be greatly appreciated!
