Pools stop flushing to tape with "Negative number of active requests" #7511

Open onnozweers opened 5 months ago

onnozweers commented 5 months ago

Dear dCache devs,

We sometimes have tape write pools that stop flushing to tape after heavy activity, usually after they have been completely filled up with precious files. After a restart of the pool, they continue writing to tape again. Using 9.2.10 but I've seen this since a few years. Now that the WLCG DC24 is ongoing, we see this problem popping up repeatedly.

When it happens, the last line in the pool's log is usually something like this:

14 Feb 2024 22:21:42 (badger2_lhcbtape) [] Flush of 0000F727C00F2D234DF0B5B70069DEE9F0F2 failed with: java.lang.IllegalArgumentException: Negative number of active requests.

Any idea what the problem could be?

I'm afraid I don't have a lot more information than this; not sure what to look for, and probably hard to reproduce because load related. The pool's info output does not show anything that helps me to understand what's wrong.

Cheers, Onno

Hi Onno,

At IN2P3, we are also affected by the same problem with LHCb since the beginning of the Data Challenge. Some migration pools stop flushing files to tape and stay stuck until a pool restart. But I don't think the flush became stuck because the pool is full of precious files. The pool became full of precious file because the flush stays stuck and files continue to be transferred on the pool. This is still related with the store counter not being always updated when a transfer is cancelled.

I opened an issue 2 years ago about this and @kofemann fixed that but I'm afraid the problem is back https://github.com/dCache/dcache/issues/6426

Thanks Adrien! I had seen your issue, but saw that it was closed as "fixed", so I assumed this would be another issue.

kofemann commented 5 months ago

Déjà vu...

For now, we have no idea if it is the same issue as #6426 or a different one. Do you have any additional information, like file deletion in parallel, cancelled flushes or so?

onnozweers commented 5 months ago

OK, I'll collect some more information.

Here is a full log of one such pool, from restart until the next time flushing got stuck.

Oops, guppy1, that node has been decommissioned... It was still in the old DNS round robin webdav.grid.sara.nl. The new DNS RR is webdav.grid.surfsara.nl and that one is OK.

[root@dcmain /var/lib/dcache/billing/2024/02]# host webdav.grid.sara.nl | grep -2 145.100.33.67
webdav.grid.sara.nl has address 145.100.33.224

webdav.grid.sara.nl has address 145.100.33.210
webdav.grid.sara.nl has address 145.100.33.226

I now made webdav.grid.sara.nl a CNAME to webdav.grid.surfsara.nl.

So, I'm guessing that LHCb was using FTS third party transfer to move this file:

/pnfs/grid.sara.nl/data/lhcb/LHCb-Disk/dataChallenge/lhcb/EXPFEB2022/TURBO/2022030213/datamover08-m/4c203272-8006-4e94-9d1c-83afe0eb4a4c.raw

To this location:

/pnfs/grid.sara.nl/data/lhcb/LHCb-Tape/lhcb/dataChallenge/lhcb/EXPFEB2022/TURBO/2022030213/datamover08-m/4c203272-8006-4e94-9d1c-83afe0eb4a4c.raw

But because they used a DNS RR with old information, the file was collected from a non-existing door node. Not a surprise that failed.

OK, so I found a problem in our setup, but no idea if it had anything to do with this issue.

I also had a look at the "Negative number of active requests" error. I looked at the timestamp, 22:21:42, and looked up in our HSM script's log to see what happened. I could see that writing to tape of file 0000F727C00F2D234DF0B5B70069DEE9F0F2 succeeded, and that it was about to exit with exit code 0.

In the billing file I can indeed see a store with error code 0 (succeeded), but also a 666:"Negative number of active requests":

But the timestamps are completely different: 17:09:29 (5 minutes after pool start) instead of 22:21:42.

Not sure if this of any help.

Hi,

This happened more and more often at IN2P3 for Atlas too in the last weeks. (dCache 9.2.14) The Store job queue stays stuck displaying 1 active store request but there is no store request in progress :

  Job Queues (active/queued)
    to store   1/0
    from store 0/0
    delete     0/0

There is no error on the flush side, no flush process running on the server. I only see usual errors with Atlas TPC transfers.

I attached the log files of the 2 pools currently stuck (cell log, pinboard, info cmd) : pool-atlas-tapebuffer-li539a.log pool-atlas-tapebuffer-li418a.log

@ageorget does this happen with stores? Can you check, if those files still exist?

ageorget commented 2 months ago

Yes, this only happens with stores on tape flush pools.

For the negative number of active requests error, sometimes it seems that the file was successfully copied on tape, the store request succeed but something went wrong when the pool tried to update the number of active requests
