I'm faced with the above mentionned problem.
System is a HP Proliant DL380 with HP SmartArray 5304-256 Controller and a HP StorageWorks 4300 disk shelf.
OS is Debian/testing with kernel 2.6.3 and LVM2.
I've created a new LV and when I try to create the FS on it, it fails when saying "Writing superblocks and filesystem accounting information:"
sar output shows that CPU is in 100% wio.
Only way to solve it is to perform a hard reboot (killing the process does nothing).
I've performed a strace of the 'mkfs.ext3' and last system call is a call to fsync (see hereafter as small part of the trace file)
Any help appreciated !
