Hi All,
Some more details:
The filesystem is ext3 and it's on an EMC Clariion
storage array (low-end SATA unit - don't know the
exact model number), with fiber-channel connection.
The cache has been disabled due to problems with the
UPS - I was assuming that this was part of the problem
but couldn't account for all of it.
There are indeed several bad things happening:
* SATA disks
* RAID-5
* No cache
But even together I didn't expect things to be *this*
bad. Am I looking for a non-existent fourth problem?
:-) My current focus is on the 512-byte writes seen
on iostat - any ideas why I could be seeing this?
Thanks
Charlotte
