XFS assertion failed: tp->t_blk_res_used <= tp->t_blk_res, file: xfs_trans.c, line: 335

[KELEMEN Peter <fuji@xxxxxxx>]

Hello,

After a couple of assertion failure-free months, here's a
reproducible one.  I can trigger this by compiling the kernel tree
on a 500M XFS partition, on a Celeron 300 MHz 128M IDE machine.
Attempting to unmount the filesystem after the assertion has been
triggered hangs the umount process:
sys_oldumount->sys_umount->do_umount->shrink_dcache_sb->iput
->linvfs_put_inode->vn_put->xfs_inactive->xfs_inactive_free_eofblocks
->xfs_ilock->xfs_ilock_ra->mraccessf->lock_wait *hang*

xfs_repair 1.2.1 reveals (-n) many errors.  I have the damaged
filesystem handy for poking around with xfs_db.

Kernel is 2.4.3-XFS 2001/04/04 15:42 CEST.

Peter
