...ext3 with Htrees. Here's a high level description of what I'm doing in versionfs_unlink: * down the isem of parent directory * compute the name of the version file * lookup the name using lookup_one_len * create the version'ed file using vfs_create * open the original file using dentry_open * copy the data from the original file to the version file * close the original file and version file * upping the isem of the parent directory * call vfs_unlink as it would have been called normally Let me know if I'm doing something wrong. Thanks, Kiran, SUNY Stony Brook.

I converted an ext4 filesystem with btrfs-convert, mounted it, and wanted to do "lzop -d ...". The result was an immediate Oops (btrfs is on LVM, on dm-crypt, on /dev/sdb which is USB-connected). mini-904.img.lzo dentry_open failed BUG: unable to handle kernel paging request at ffffffcd IP: [<c01b5f36>] fput+0x6/0x30 *pde = 00575067 *pte = 00000000 Oops: 0002 [#1] SMP last sysfs file: /sys/block/sda/removable Modules linked in: kqemu sha256_generic aes_i586 aes_generic cbc usb_storage dm_crypt btrfs zlib_deflate...

Hi there, i''m trying to send/receive a snapshot of my home dir for some time now, but in the end it always fails because the maximum number of open fd''s is exceeded. Kern log says: "6,7226,15012711248,-;VFS: file-max limit 799969 reached" My setup is as follows: Kernel: 3.9-rc5 btrfs-progs: compiled from git commit: commit

I got this.. The system was usuable, but not very. If I tried to access the ext3 volume, it would hang. Reboot hung too, complaining about too many open files. Any ideas? I have no idea what triggered it; this is a big file/web/mail server, with all of that on the ext3 volume. And I've never run ksymoops before, but I think I did it right. - Josh Assertion failure in
