Re: [OpenAFS] AFS client hanged
Hi Qiulan, Can you please confirm that there are no other "INFO: task ... blocked for more than 120 seconds" messages? This is rather curious, since of the three tasks listed here, one is waiting trying to acquire the AFS_GLOCK, and the other two are sleeping (having dropped the AFS_GLOCK in order to sleep_. So if something is holding on to the AFS_GLOCK that keeps the afs_callback task from acquiring it, that task would be expected to also show up in the list of blocked tasks as output by the kernel.

The issue appear on many clients in the cluster but not at the same time. Every morning we check the status of compute nodes we got some of them hanged. Also, we found some clients failed to access some file located in AFS. The file looks well by "ls". But it failed to read it. I use strace command to trace the cp command to know the operation was stuck after reading several KB. It's weird. And from server side using tcpdump to know the package sent to server only version information without data. It seems like the client think the cache data is the latest one. Actually the cache is dirty . But the data access didn't trigger data fetch. 17:40:07.167220 IP lhws136.ihep.ac.cn.afs3-callback > 202.122.35.133.afs3-fileserver: rx version (29) 17:40:07.171580 IP bws0666.ihep.ac.cn.afs3-callback > 202.122.35.133.afs3-fileserver: rx version (29) 17:40:07.196307 IP acc-ap18.ihep.ac.cn.afs3-callback > 202.122.35.133.afs3-fileserver: rx data fs call setlock fid 536887265/30/43 (48) 17:40:07.222616 IP lxslc604.ihep.ac.cn.afs3-callback > 202.122.35.133.afs3-fileserver: rx data fs call setlock fid 536887265/30/43 (48) 17:40:07.240442 IP bws0420.ihep.ac.cn.afs3-callback > 202.122.35.133.afs3-fileserver: rx version (29) > > We run these packages on a lot of SL6 and SL7 systems, and the issue reported > here at least isn't common.

We run these packages on a lot of SL6 and SL7 systems, and the issue reported here at least isn't common. We seem to have a project with a usage pattern able to provoke hangs though. That has yet to be investigated. It was about something like using zsh tab completion in a git repo... ___ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info
