I created a small volume for testing and ran the simplest dump/restore
I could think of:
$ mkfs -t xfs -f /dev/homerdata/testvol
$ mount /dev/homerdata/testvol /mnt/xfstest/
$ touch /mnt/xfstest/test
$ xfsdump -J -v 5 - /mnt/xfstest 2>dumperr| xfsrestore -J -v 5 - \
/mnt/pub/Backups/restore_test/ > restoreout
Bus error
This is the stock 2.4.18 with the xfs-1.1-2.4.18-all.patch applied.
Both the source and target are on lvm.
I'm using xfsdump-2.0.1 and xfsprogs-2.0.3.
Here is the dump output (227 lines):
