I'm trying to dedupe the two large XFS filesystems on which I have DVR recordings, so that I can walk around amongst the available HDDs and create new filesystems under everything. Every time I rm a file, the filesystem blows up, and the driver shuts it down. Some background: At the moment, I have 2 devices, /dev/sdd1 mounted on /appl/media4, and /dev/sda1 mounted on /appl/media5, and a large script, created by hand- hacking the output of a perl dupe finder script. The large script was mangled so that it would remove anything that was a dupe from media4, unless the file was an unlabeled lost+found on media5, and had a name on media4. In that case, I removed the file on media5, and then moved it from media4 to media5. After the hand-hacking on the script, I sorted it to do all the rm's first, and then all the mv's, to make sure free space when up before it went down. And, of course, when I ran the script, it caused the XFS driver to cough and die, leading to error 5s and gnashing of teeth. I unmounted media5, remounted it (which worked), and unmounted it again to run xfs_repair -n. That found one inode that was pointing somewhere bogus (and I apologize that I can't copy that in; I was running under screen, and it doesn't cooperate with scrollback well). I ran an xfs_repair without -n, and it found and fixed the one error without complaint. I mounted and unmounted it successfully (nothing notable in dmesg), and reran xfs_repair -n, which, this time, ran without any problems reported. So I remounted the filesystem, and again tried to run the script. And again, it tripped something, and the filesystem unmounted, and here's the dmesg output from the first and second trips: First time: [169324.654803] XFS (sdd1): Ending clean mount [1278872.471310] ccbc0000: 41 42 54 42 00 00 00 04 df ff ff ff ff ff ff ff ABTB............
