Re: mount: Function not implemented

Just for document purposes...

sandeen mentioned to do,

dd if=/dev/hdb bs=512 count=128  | hexdump -C | grep XFSB

00000000  58 46 53 42 00 01 00 00  00 00 00 00 00 3a 38 b0  |XFSB.........:8.|
00007e00  58 46 53 42 00 00 10 00  00 00 00 00 03 a3 88 a0  |XFSB............|
128+0 records in
128+0 records out
65536 bytes (66 kB) copied, 0.0283236 seconds, 2.3 MB/s


So recreating the partition should work. First we backup the sectors.

dd if=/dev/hdb bs=512 count=256 of=backup_sectors

Then the partition is recreated using fdisk /dev/hdb, option n -> p (primary
-> 1 for partition 1 -> default first cylinder 1 -> default last cylinder
30401 -> (w)rite table to disk and exit. :)

Running xfs_check /dev/hdb1 returns no errors, which was hoped. Mounting the
partition shows ALL files present! So everything is working back to normal.

Thanks to XFS team and sandeen! :)
