I had a filesystem crash when I tried to upgrade ghc to version 4.7.2 during stage2 of building with llvm use flag. This was on kernel 3.5.7-gentoo on an i686 32-bit machine. I have upgraded kernel on this machine to 3.7.10-gentoo and tried again. This time I looked at dmesg to see the reason for the crash: [42726.783173] vmap allocation for size 4194304 failed: use vmalloc=<size> to increase size. [42726.783192] vmap allocation for size 4194304 failed: use vmalloc=<size> to increase size. [42726.783204] vmap allocation for size 4194304 failed: use vmalloc=<size> to increase size.

Reproducible: Didn't try Steps to Reproduce: 1. format /var with xfs filesystem 2. type: USE="llvm" emerge ghc 3. wait one hour or so Actual Results: crash, possibly damage to data Expected Results: no crash After previous crash I've lost all my KDE settings (how come? this will remain a mystery for me forever), so please don't expect much of help in this issue from me - this is potentially disasterous operation, so I won't try to do it again. This system has a little RAM: $ free total used free shared buffers cached Mem: 2067436 1774552 292884 0 4 1311060 -/+ buffers/cache: 463488 1603948 Swap: 2104508 652576 1451932 However, amount of RAM should not act as an excuse for leaking filesystem driver. I got a feeling that XFS suffers from lack of maintenance nowadays, recently I used to have repeating problems with crash on unmount when I was using 3.5.7 kernel. So far it did not happend with 3.7.10 but I got a feeling that it's just a matter of time. Things like this did not happend to XFS in the past (say, year ago), no matter how much RAM was installed in the host.

There are some reports of this through the years, with data loss being a possibility. Most reporters understandable feel like you do and do not want to test further and risk losing data or worse. I'm closing this as upstream, as this really should go there. If you want to pursue it further with them, please see: http://xfs.org/index.php/XFS_FAQ#Q:_What_information_should_I_include_when_reporting_a_problem.3F and: http://oss.sgi.com/bugzilla/buglist.cgi?product=XFS&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED If you do open a bug, they will probably look for to you for more testing. Please post the link to the bug if that's the route you choose to take.
