Hi,
I have other information.. the behavior started to be 100% reproducible on my
machine: every time I added a file I found it in the past snapshot. But it
appeared after a delay, ranging from 1 to about 20 seconds!
% hammer snapls /home/attic/
Snapshots on /home/attic/ PFS#2
Transaction ID Timestamp Note
0x0000000000000000 2017-04-06 09:57:34 CEST -
% pwd
/home/attic
% touch a_new_file
% ls .@@0x0000000000000000
disk_stats.txt
The file isn't in the snapshot yet. But if a i keep repeating the ls command
after a few seconds I find it:
% ls .@@0x0000000000000000
a_new_file disk_stats.txt
Then I decided to run hammer cleanup:
# hammer cleanup
[... Output snipped ...]
cleanup /home/attic - handle PFS#2 using /var/hammer/home/attic
snapshots - run
prune - run
rebalance - run..
reblock - run....
recopy - skip
[... Output snipped ...]
Now I have a new snapshot but the old snapshot is gone:
% hammer snapls /home/attic/
Snapshots on /home/attic/ PFS#2
Transaction ID Timestamp Note
0x00000001186c2200 2017-04-08 18:25:50 CEST -
This new snapshot doesn't exhibit the behavior described above: I can add and
delete files in the main directory and the snapshot doesn't change.
Sadly, now I have no access to the old snapshot to further diagnose the
problem. I didn't think hammer cleanup would delete a snapshot from two days
ago.
Kind regards,
Andrea
