Summary: XFS stucks in io_schedule after creating a sparse file
greater than space left
Kernel Version: 2.6.18-rc6
Status: NEW
Severity: high
Owner: xfs-masters@xxxxxxxxxxx
Submitter: oehmes@xxxxxxxxxxxxxx
Most recent kernel where this bug did not occur: NA
Distribution: Fedora
Hardware Environment: Intel Duo Core Laptop
Software Environment: Fedora Core 6
Problem Description: as soon as you fill a sparse file bigger than the
filesystem has space left, the next sync request will hang
Steps to reproduce: create a bunch of sparse files on a lvm mounted xfs
filesystem and generate data in them, i did it with cp --sparse=always and
copied a already filled file into a new file in the same filesystem, the target
was bigger than i thought and hit disk full. then i did a sync and this was
hanging forever .
i made a echo t> /proc/sysrq-trigger which indicated that it hangs in
io_scheduler i will add a attachment with the dmesg output
