Hello,
I have a snv101 machine with a three disk raidz pool which allocation
of about 1TB with for no obvious reason, no snapshot, no files,
nothing. I tried to run zdb on the pool to see if I got any useful
info, but it has been working for over two hours without any more
output.
I know when the allocation occurred, I issued a mkfile 1024G command
in the background, but changed my mind and killed the process, after
that the 912G was missing (don't remember if I actually removed the
test file or what happened). If I copy a file to the /tank filesystem
it uses even more space, but that space is reclaimed after I remove
the file.
I could recreate the pool, it is empty, but I created it to test the
system in the first place so I would like to know what's going on. I
have tried to export and import the pool, but it stays the same.
Any ideas?
