I have a ZFS filesystem with compression turned on. Does the "used" property
show me the actual data size, or the compressed data size ? If it shows me the
compressed size, where can I see the actual data size ?
I also wonder about checking status of dedupe - I created my pool without
dedupe, and continue to NOT enable dedupe - from zpool history, we see:
zpool create -f -O atime=off -O setuid=off -O exec=off -m /mnt/pool pool raidz3
da0 da1 da2 da3 da4 da5 da6 da7 da8 da9 da10 da11
Later, I enabled dedup for just a single filesystem on this pool:
zfs set dedup=on pool/dataset
and now, I see in 'zpool list' a value for dedupratio:
pool dedupratio 1.65x -
Why do I see a value here ? Isn't dedupe still OFF for the pool as a whole ?
I do NOT want to enable dedupe for the entire pool.
Also, why do I not see any dedupe stats for the individual filesystem ? I see
compressratio, and I see dedup=on, but I don't see any dedupratio for the
Did turning on dedupe for a single filesystem turn it on for the entire pool ?
