Howdy,
been reading this thread and am pretty intrigued, ZFS is much more than
i thought it was.
I was wondering though does ZFS work as a multiple client single storage
cluster such as GFS/OCFS/VMFS/OrangeFS ?
I was also wondering if anyone could share their experience with ZFS on
iscsi - especially considering the readahead /proc changes required on
same system ?
thanks!
