All of the OSTs and MDTs are "independently managed" (have their own connection
state between each client and target) so this should be possible, though I
don't know of sites that are doing this. Possibly this makes sense to put NVMe
flash OSTs on ldiskfs, and HDD OSTs on ZFS, and then put
Thank you Andreas! How about mixing OSTs? The requirement is to do RAID
with small volumes using ZFS and have a large OST. This is to reduce the
number of OSTs overall as the cluster being extended.

Yes, some systems use ldiskfs for the MDT (for performance) and ZFS for the
OSTs (for low-cost RAID). The IOPS performance of ZFS is low vs. ldiskfs, but
the streaming bandwidth is fine.

Hi,
Could we mix ZFS and LDISKFS together in a cluster?
