 Description

I just got my test bed back and tried this out.

lctl list_param *.OST000.readcache

obdfilter.lustre-OST0000.readcache_max_filesize

obdfilter.lustre-OST0002.readcache_max_filesize

osd-ldiskfs.lustre-OST0000.readcache_max_filesize

osd-ldiskfs.lustre-OST0002.readcache_max_filesize

Now if you try obdfilter version it gives a warning not to use it anymore.
