"zfs hold" and "zfs send" on a readonly pool
...port with readonly=on. I struck an unexpected problem: modern "zfs send" uses the "zfs hold" feature to lock the snapshots from destruction. However, on a readonly pool the holds don''t succeed and the send never occurs: root at openindiana:~# zfs send -R rpool/ROOT/oi_148a at 20111028-01 | \ zfs recv -vnFd pool/rpool-backup cannot hold ''rpool/ROOT/oi_148a at 20110317-03'': pool is read-only cannot hold ''rpool/ROOT/oi_148a at 20110319-01'': pool is read-only cannot hold ''rpool/ROOT/oi_148a at 20110322-01'': pool is...

I''m doing a large amount of video streaming from a storage pool while also slowly continuously writing a constant volume of data to it (using a normal file descriptor, *not* in O_SYNC). When reading volume goes over a certain threshold (and average pool load over ~50%), ZFS

Does raidzN actually protect against bitrot? If yes - how?
"Does raidzN actually protect against bitrot?" That''s a kind of radical, possibly offensive, question formula that I have lately. Reading up on theory of RAID5, I grasped the idea of the write hole (where one of the sectors of the stripe, such as the parity data, doesn''t get written - leading to invalid data upon read). In general, I think the same applies to bitrot of
