You're welcome to follow your heart on choice of filesystem of course, but without knowing what happened to your storage, it's a little bit of a stretch to blame xfs. Just based on: > xfs_check: /dev/loop51 is not a valid XFS filesystem (unexpected SB magic number 0xeb639010) it appears that something scribbled all over your storage (i.e. the file backing it - what was that stored on?) What it was that did the scribbling, and how much it scribbled is unknown, and it may or may not have been more significant than whatever hit your ext4 partitions. I do not think you encountered an xfs bug; something else severely damaged your block device. -Eric > Niccolò > > _______________________________________________ > xfs mailing list > xfs@xxxxxxxxxxx > http://oss.sgi.com/mailman/listinfo/xfs > _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
