OK, this seems to be deterministic and not a HW-problem..
I am testing xfs on a brand new linux file server having a 1.1T xfs
filesystem in dual processor (Intel III Xeon 1GHz) motherboard
with 1G memory.
When using xfs with linux kernel 2.4.6 (compiled with egcs-2.91.66) and
Linux software RAID5 all processes accessing the /dev/md0 device lockup in
D-state when trying to write files from network with tar (kupdated, tar,
pagebuf_daemon and /bin/sync) typically after few hundred megabytes have
been written. Kdb tells me that all processes are hanging forever in
All SCSI drives are still working, when accessed directly
through /dev/sda-g.. Oops, seems that they too get stuck after a while
(perhaps trying to write some pages to disk).
The same problem does not come up when using ext2.
/bin/free tells me this:
total used free shared buffers cached
Mem: 899328 324772 574556 0 134952 115272
-/+ buffers/cache: 74548 824780
Swap: 2097136 0 2097136
Only thing I can do, is to reboot with /sbin/reboot -nf.
I've have seen other reports in mailing list with this kind of problem.
Are there known solutions? I think I might try the cvs version...
