Actually I was wrong with the usage - I was testing whether /home is in use with "fuser -m /home". I've added the "-m" argument out of habit. Actually, /home seems to be unused - plain "fuser /home" shows no accessing processes. So the cause seems to be different.
The symptoms are: # fuser /home # mount /dev/hda6 /home/ mount: /dev/hda6 already mounted or /home/ busy # mount -v -t xfs /dev/hda6 /home/ mount: /dev/hda6 already mounted or /home/ busy # hexdump -C /dev/hda6 | head 00000000 58 46 53 42 00 00 10 00 00 00 00 00 01 96 52 e0 |XFSB..........R.| 00000010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 00000020 c9 e3 cb ee 47 e0 11 d7 9f 33 ed 99 1e fa c2 d0 |....G....3......| 00000030 00 00 00 00 00 d0 00 04 00 00 00 00 00 00 00 80 |................| 00000040 00 00 00 00 00 00 00 81 00 00 00 00 00 00 00 82 |................| 00000050 00 00 00 10 00 10 00 00 00 00 00 1a 00 00 00 00 |................| 00000060 00 00 0c b2 20 94 02 00 01 00 00 10 00 00 00 00 |.... ...........| 00000070 00 00 00 00 00 00 00 00 0c 09 08 04 14 00 00 19 |................| 00000080 00 00 00 00 00 05 c7 80 00 00 00 00 00 01 de a2 |................| 00000090 00 00 00 00 00 32 0f 26 00 00 00 00 00 00 00 00 |.....2.&........| A sidenote to Stephen: On POSIX systems (including Linux) you actually _can_ delete files and directories that are in use, since they are identified by their inode numbers. So if your /home directory is used by some processes, you can still rmdir or "rm -rf" it and it will disappear. You can mkdir a new /home, and it will be a different one, and the processess holding the old one will still see the old one. Its space will be reclaimed in the filesystem when the last process to use it will close its handle. You can test a filesystem object's usage using the "fuser" command. But to be used as a mount point, a directory cannot be in use. -- xfs /home cannot be mounted on boot https://bugs.launchpad.net/bugs/153600 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
