Problems with volumes v1 and v10 of storage system Pica -- NOW FIXED

2016-07-01

Since about four o'clock on Friday morning, volumes v1 and v10 of Pica, containing project directories, has been unresponding.

Also volumes v11 and v12 may be affected by the problem, before it is solved.

We are investigating.

At 0915 hours we restarted part of Pica, and that fixed the problem. But we are sorry to say, that there is some risk that jobs may have crashed due to the problems.

It seems like some, yet unidentified, user is hitting Pica with too many read/write requests, so the problem may re-appear. Sometimes we find the culprits, most of the time not.
