Summary: when tested with fsstress in scsi, the process is
locked.
Product: Linux XFS
Version: Current
Platform: IA32
OS/Version: Linux
Status: NEW
Severity: blocker
Priority: High
Component: XFS kernel code
AssignedTo: xfs-master@xxxxxxxxxxx
ReportedBy: wddi_1976@xxxxxxxxxxxx
What kernel are you using:
2.4.19-xfs
Where did the XFS code come from? (CVS, Linus, your distribution, etc):
CVS kernel
Description of Problem:
Just now, I tried that test on the cvs kernel again, it did not
oops anymore,
but it is locked after a while, I studied all the process trace of
the system,
it seems that only one process is locked, the trace is here.
__down()
__down_failed()
[xfs].text.lock.xfs_log
xlog_state_get_iclog_space()
xlog_write()
xfs_log_write()
xfs_trans_commit()
xfs_attr_rolltrans£¨£©
xfs_attr_mode_addname()
xfs_attr_set()
linvfs_setxattr()
setxattr()
sys_lsetxattr()
system_call()
(It seems that some process was wirting the log to disk. but no other
process was writing to disk at this time)
How Reproducible:
Run the shell command
/fsstress -d /mnt/tmp \
-f allocsp=0 \
-f freesp=0 \
-f bulkstat=0 \
-f bulkstat1=0 \
-f resvsp=0 \
-f unresvsp=0 \
-f attr_set=100 -f attr_remove=100 \
-S -p 1 -n 10000
(A 200m xfs partition is mounted at /mnt/tmp, use scsi)
fsstress is the program provided in xfstest package.
Actual Results:
the process was locked.
