zfsadm shrink is faster and less disruptive. Nevertheless, shrinking is not automatic like growing is (can be). The fact that one can compress, decompress, encrypt, decrypt, grow, or shrink zfs files in-place and in-use implies to me that the zfs developers are pretty sharp. sas On Tue, Aug 8,

If a user greatly reduces their file usage, you can create a new home directory, copy the remaining files over, and release the old directory. If it's a separate z/OS file system, you get the space back. On Tue, Aug 8, 2023, 07:11 Jack Zukt wrote: > As someone pointed out, it is only one more us

As someone pointed out, it is only one more user file and I suppose that you no not manage your space by restricting the number of user files. As it has also been noticed, it can, and will be HSM migrated. And when you delete a RACF userid the zfs file goes with all the others, there is no USS dire

We use automount with auto created ZFSs for each user. We set the size so it won’t grow beyond our settings. Works great. On Mon, Aug 7, 2023 at 7:57 AM Rick Troth wrote: > > However it is not reality show or beauty contest, rather I'd like to > see some real advantages of automount. > > La

Obviously it is not big deal. Yes, automount or not-automount is not the question (Hamlet). :-) It is just my opinion that automount require some setup and provide no value. And of course this is discussion forum, so I expect other opinions or arguments. This is kind of learning opportunity, whi

Every user on our system has dozens of "personal" files, ISPF-related, DDIR, etc. One more is no big deal. And if a user blows up their home filesystem, it's a minor issue (1 user), not a critical one (all users affected). I also do not want to manage space usage in the filesystems. I appreciat

Regarding automount feature: IMHO it is less than useless. - It require some effort to establish and manage (including storage adm.) - It wastes space, because even smallest empty home directory occupies first extent of the ZFS/HFS. - Space (extents) taken by some large files and then deleted is
