How to retrieve your corrupted or deleted /t3home
and /work
files
Every user can retrieve from snapshots corrupted or deleted files from
/t3home
or
/work
.
Choose a snapshot dir and copy back either to
/t3home/$USER
(or
/work/$USER
) what you need by
cp
command.
/t3home example:
$ cd /t3home/$USER/.snapshot
$ ls
daily.2019-02-26_0010 daily.2019-02-27_0010 monthly.2019-02-01_0010 weekly.2019-02-24_001
/work snapshot location example
Since October 2019 there is an option for user to create a snapshot of workspace.
Please contact administrators for more information.
$ cd /work/$USER/.zfs/snapshot
[martinelli_f@t3ui01 ~]$ cd /work/$USER/.zfs/snapshot
[martinelli_f@t3ui01 snapshot]$ ls -l
dr-xr-xr-x 1 root root 0 Dec 10 18:44 zfssnap-day-20161207-011142 <-- Max 2 past days
dr-xr-xr-x 1 root root 0 Dec 10 18:44 zfssnap-day-20161208-014735
In a case of
/work
please be aware regrding deleted files that are still referenced in snapshots. In that case deleted files are saved in snapshot. And snapshot grows in space correspondingly.
This affects your
/work
space quota while snapshot is a PART OF QUOTA.
Till snapshot itself is deleted you won't not get a free space .
Over quota running often means that you're frequently adding/removing big files in your
/work
. Instead please stage data to UI/WN
/scratch
or the
/pnfs
areas for that purpose!
