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. _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
