We're using amanda and GNU tar (1.13.25) to backup a new Netapp to a
Solaris 8 Sun.
The first pilot users moved to the Netapp went fine, and then amanda
started acting up. The symptom was tar was grinding on one of the CPUs
and amanda was marking the host as not responding. The host happens to
also be the amanda server, but I don't think that is relevant. truss
indicated that there were NO system calls being made by the process.
Captured the amanda ps process being used and duplicated it on the command
line, adding the --verbose flag. What I've traced it back to, is one of
the users I migrated to the Netapp had a very long file name in his .kde
http cache
./xxx/.kde/share/cache/http/r/www.redhat.com_docs_manuals_linux_RHL-7.3-Manual_getting-started-guide_figs_disks_xcdr1.png_5a13234a
Obviously nothing he tried to create. Now the pathname is 131 chars long,
and the basename of the file is 101 chars. By renaming the file tar went
along happily.
I did some web and Amanda archive searches looking for a reference to this
problem and came up with nothing on point. Of course I always second
guess myself on the search criteria used.
Did I miss a known issue with gnu tar? And I thought it odd that the
"error" condition would be to sit and spin on a CPU.
Has anyone else seen similar behavior?
Thanks,
Murf
