1.8.4 and write-through cache
...stacks all over the place, crawling along and
generally making our lustrefs unuseable.
After trying different kernels, raid card drivers, changing write back
policy on the raid cards etc. the solution was to
lctl set_param obdfilter.*.writethrough_cache_enable=0
lctl set_param obdfilter.*.read_cache_enable=0
on all the nodes with the 3ware cards.
Has anyone else seen this? I am completely baffled as to why it only
affects our nodes with 3ware cards.
These nodes were working very well under 1.8.3...
