I can reproduce a problem in patch 44 too. It takes my copy test 20

is 100 times faster than patch 43 but I will let patch 43 spin all
weekend on a couple machines to verify that patch 43 does not hang.
Details, please. What's your "copy test"?

Cheers,

Micheal found the problem using a simple copy, so I am using copy-like test.
I have hung patch 44 with fsstress but I am currently using the simple
perl scripts from bugzilla bug 922, but I do not do the silly step of
reducing the log to an abnormal amount.
Just mkfs the filesystem
Create the the test files. the creation script:
http://oss.sgi.com/bugzilla/attachment.cgi?id=304
Run the test script:
http://oss.sgi.com/bugzilla/attachment.cgi?id=305
----
This test seems to stress the log much like xfstest 273 only it runs
forever.
I have a 32 bit machine:
meta-data=/dev/sda4 isize=256 agcount=4, agsize=601152 blks
= sectsz=512 attr=2
data = bsize=4096 blocks=2404608, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal bsize=4096 blocks=2560, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
and 64 bit machines with a little larger filesystems:
meta-data=/dev/sdb2 isize=256 agcount=4, agsize=2622080
meta-data=/dev/sda2 isize=256 agcount=4, agsize=4194432 blks
= sectsz=512 attr=2, projid32bit=1
= crc=0
data = bsize=4096 blocks=16777728, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal bsize=4096 blocks=8192, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
I am running patch 43, I know that patch 44 will hang in about 20
minutes. One 64 bit machine is at hour 50 on patch 43. Monday I will
stop the test one of the machines and try to account for the log space.
--Mark.
