Mass Storage (/pnfs) /pnfs has sometime issues

Hello,

For the last few days, /pnfs is having performance issues, while some storage nodes can't serve files. We have not identified the cause yet.

Mainly cd/ls becomes slow, and only a restart of the service makes it work fast again. Also, a couple of storage nodes have a hard time serving files (hence why some of your files have issues), this usually solves itself after a while.

Cheers, The T2B IT Team

Mass Storage (/pnfs) Some issues with mass storage /pnfs [Rucio & Crab]

Hello,

Several users have reported that:

1/ Rucio does not allow copies to our RSE with error: Details: RSE excluded; not available for writing.

2/ Crab also complains that tasks can't be started because you are not allowed to write on your home directory on our site: Checkwrite Result: Unable to check write permission in /store/user/rougny on site T2_BE_IIHE

We are investigating both issues.

On the other hand, standard grid commands on your files (eg gfal-copy) seem to work without any issues.

Cheers, Romain

  • Dear all,

    After consulting with central CMS IT services, it seems that they have resolved the problem from their end. We also received confirmation from users that the rucio and crab indeed work as expected again.

    Kind regards,
