...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 ! Paul write(1, "done\n", 5done...

To me, this says the simple directory scan is fairly "light" at the system level, and most of the cycles get used by the app. Sar says: SunOS elsbeth 5.8 Generic sun4u 03/08/00 12:56:32 %usr %sys %wio %idle 12:56:33 2 9 9 80 12:56:34 5 3 1 91 12:56:35 0 0 0 100 12:56:36 0 0 0 100 (Yes, I was testing on Solaris 8 at work (;-)) The open and first readdir caused wait-io, the rest grabbed data from a buf...

How can I tell if this is normal behaviour? Oracle imports are horribly slow, an order of magnitude slower than on the same hardware with a slower disk array and Solaris 9. What I can look for to see where the problem lies? The server is 99% idle right now, with one database running. Each sample is about 5 seconds. I''ve tried setting kernel parameters despite the docs saying that
