Hi all, so I went ahead and updated my ~7.2 file server to the new ZFS goodness, and before running any further tests, I already discovered something weird and annoying.
I'm using a mirror on GELI, where one disk is usually *not* attached as a means of poor man's backup. (I had to go that route, as send/recv of snapshots frequently deadlocked the system, whereas a mirror scrubbing did not) r...@coyote:~# zpool status pool: tank state: DEGRADED status: The pool is formatted using an older on-disk format. The pool can still be used, but some features are unavailable. action: Upgrade the pool using 'zpool upgrade'. Once this is done, the pool will no longer be accessible on older software versions. scrub: none requested config: NAME STATE READ WRITE CKSUM tank DEGRADED 0 0 0 mirror DEGRADED 0 0 0 ad4.eli ONLINE 0 0 0 12333765091756463941 REMOVED 0 0 0 was /dev/da0.eli errors: No known data errors When imported, there is a constant "tasting" of all devices in the system, which also makes the floppy drive go spinning constantly, which is really annoying. It did not do this with the old ZFS, are there any remedies? gstat(8) is displaying the following every other second, together with a spinning fd0 drive. dT: 1.010s w: 1.000s filter: ^...$ L(q) ops/s r/s kBps ms/r w/s kBps ms/w %busy Name 0 0 0 0 0.0 0 0 0.0 0.0| fd0 0 8 8 1014 0.1 0 0 0.0 0.1| md0 0 32 32 4055 9.2 0 0 0.0 29.2| ad0 0 77 10 1267 7.1 63 1125 2.3 31.8| ad4 There is no activity going on, especially md0 is for /tmp, yet it constantly tries to read stuff from everywhere. I will now insert the second drive and see if ZFS shuts up then ...
