[lustre-discuss] Disk quota exceeded while quota is not filled

[David Cohen]

Hi,
I'm running Lustre 2.10.5 on the oss and mds, and 2.10.7 on the clients.
While inode quota ons mdt worked fine for a while now:
lctl conf_param technion.quota.mdt=ugp
When, few days ago I turned on quota on ost:
lctl conf_param technion.quota.ost=ugp
Users started getting "Disk quota exceeded" error messages while quota is
not filled

Actions taken:
Full e2fsck -f -y to all the file system, mdt and ost.
lctl lfsck_start -A -t all -o -e continue
turning quota to none and back.

None of the above solved the problem.

lctl lfsck_query

[lustre-discuss] Commvault lustre backup / archive

[Andrew Elwell]

Hi folks,

I see from their release notes that Commvault should be able to act on
changelogs for backup. Anyone here doing so? Any gotchas to worry about? Is
it better than scanning (ugh) and making the MDS unhappy?

Similarly how good is the archive functionally? Does it play well with
lustre HSM design?

(Feel free to contact me off list if you'd rather) - I tried to get info
out of our local reseller without much success...

Andrew

[lustre-discuss] [LAD'20] Call for Paper & Save the date!

[quentin.bouget]

Dear Lustre Community,

Due to the ongoing pandemic, LAD will be a virtual event this year.
The usual social event and dev' summit are canceled... But admissions 
are free of charge! \o/


For this year's edition of LAD, we plan to broadcast 2h of pre-recorded 
presentations, twice a day at 8AM and 4PM UTC (same content both times), 
from October 13 to October 15.


CEA will set up a short-lived chat platform so that attendees may ask 
questions during the broadcasts, and also after them.


Speakers will be expected to attend at least one of their presentation's 
broadcast, to answer live questions. They will also be expected to 
asynchronously answer questions from the other broadcast.


As usual, presentations will be uploaded on youtube (shortly) after the 
event.


We hope the time slots we picked will prove acceptable to everyone.
Please let us know if we missed anything obvious.

*@speaker-candidates*, please submit a summary of your presentation on 
easychair  for review 
/before/ September 13.
Further information on the submission and review process is available 
here .


*@attendees*, registration will open as the agenda gets published, on 
September 21.


--

We would like to thank OpenSFS and EOFS for their help.

Cheers, stay safe,
Quentin
