Oh I forgot the more important question.
Importing all the user quota settings; Currently as a long file of "zfs
set" commands, which is taking a really long time. For example,
yesterday's import is still running.
Are there bulk-import solutions? Like zfs set -f file.txt or similar?
If not, I could potentially use zfs ioctls perhaps to write my own bulk
import program? Large imports are rare, but I was just curious if there
was a better way to issue large amounts of "zfs set" commands.
As with most other zfs(1m) commands, the slow part is waiting for a txg to
sync out. If you do many requests in parallel, many of them will wait for
the same txg, so the quickest way would be to do batches of ~1000 concurrently:
for (user, quota) in file:
zfs set userqu...@user=quota &
if i++ % 1000 == 0
wait
batch size should be proportional to available system memory.
If you develop an actual script based on this, I'm sure others here could use
it too!
