[zfs-discuss] Find out which of many FS from a zpool is busy?
Hi all, sorry if this is in any FAQ - then I've clearly missed it. Is there an easy or at least straight forward way to determine which of n ZFS is currently under heavy NFS load? Once upon a time, when one had old style file systems and exported these as a whole iostat -x came in handy, however, with zpools, this is not the case anymore, right? Imagine zpool create tank . (many devices here) zfs set sharenfs=on tank zfs create tank/a zfs create tank/b zfs create tank/c [...] zfs create tank/z Now, you have these lovely number of ZFS but how to find out which user is currently (ab)using the system most?
