Cta-admin dr ls failed when a file is being transferred

biyujiang · 16 2021 00:49

Hi, there,
After I upgraded cta to 4.2-3 from 4.0-2, I notice that when I run cta-admin dr ls with a file being transferred, it will crash and the error is:

210916 08:33:36 256076 ssi_Pb::Request: pid:256068 tid:140486964729600 ProcessResponseData(): fatal error from XRootD framework
Unable to read stream /ctafrontend; GetBuff failed: basic_string::at
library drive host desired request status since vid tapepool vo files data MB/s session priority activity age reason disk_system_name reserved_bytes

Meanwhile, the cta-taped will throw an exception which may cause the backup fail. Some error log like

But the eos don’t recognize the archive result as Files archived but eoscta disagrees.

We don’t know what the problem is. Did anyone else have such problems? Thanks.

Cheers,

Hi Yujiang,

Thanks for letting us know. This is a recent regression which will be fixed in the next release. More details in the following ticket;

Oliver.

biyujiang · 17 2021 03:02

OK. I noticed the bug. And a new 4.2-2 was released yesterday. I tried the new version, but have a similar problem of running cta-admin dr ls when an archivial is running:

The archivial request is finished successfully, however.

okeeble · 17 2021 07:33

Hi,

Tag 4.2-2 was made before the fix was committed. We are running 4.1-1 in production and will not deploy 4.2-2.

We are contemplating making a public binary release which would contain what we are running in production here at CERN, would that be useful to you?

Oliver.

biyujiang · 17 2021 08:46

Yeah. A stable public release would make it clear to us, and we can keep up to the latest stable release. Thanks.
