-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello,
I have an odd problem going on. I am an admin for a major AFS installation at a university in the Midwest. We have a couple of supercomputers acting as AFS clients, but it seems like there's an intermittent problem where operations in AFS crash a node. The logs on the clients seem to indicate something to do with a failure to write to an inode in the cache before the crash. Files are written successfully to the data subdirectories of the cache, however. The cache sits in /tmp, but is on a simple ext3 filesystem, so nothing is funny there. The error we see always points to the same line in the same file in the OpenAFS source, osi_file.c, line 71: openafs: Can't open inode 1952804 - ----------- [cut here ] --------- [please bite here ] --------- Kernel BUG at osi_file:71 Also, the inode referenced in the error messages always can be found somewhere in the AFS cache directory tree. We're running openafs-1.4.4 client on RHEL 4 on Power and x86_64. The nodes also run Lustre and GPFS at the same time as AFS. One theory is that one or the other of those may be interfering at a kernel level, but that's really hard to prove at the moment. The kernel we run on these machines is the lustre-patched 2.6.9 kernel. Here's some information from one of the systems: # uname -a Linux b001 2.6.9-55.EL_lustre-1.4.1.quarry1 #1 SMP Tue Oct 2 08:54:17 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux # rpm -qa | grep openafs openafs-1.4.4-rhel4.2 openafs-docs-1.4.4-rhel4.2 openafs-kernel-source-1.4.4-rhel4.2 openafs-client-1.4.4-rhel4.2 openafs-krb5-1.4.4-rhel4.2 openafs-authlibs-1.4.4-rhel4.2 # rpm -qa | grep gpfs gpfs.msg.en_US-3.1.0-13 gpfs.base-3.1.0-13 gpfs.gpl-3.1.0-13 gpfs.docs-3.1.0-13 One other odd thing is is that it seems like not all the nodes have a /usr/vice/cache/VolumeItems file at all, it was never created it seems, and others have a zero length file there. I don't know if this is related, however. Thanks for any help!
