[Pc_Support] SuSE 9.2 Reiserfs/NFS problems ....

[William A. Mahaffey III]

.... I have a 2.4 GHz P4 running SuSE 9.2, box stock, kernel 2.4.20-4GB, 
using reiserfs for all native filesystems (Std. SuSE practice). I have 
the system disk (20 GB WD, generic IDE 100) partitioned w/ 2 partitions, 
/ & swap. I have /home on a separate HDD, 160 GB Samsung, about 6 mos. 
old, from NewEgg. It is partitioned as 1 big partition, taking up the 
whole drive. I use this box to backup several other machines on my LAN, 
using TAR (1) to create gzipped tar archives in an archive directory 
under /home (on the 160 GB drive). That process kicks off every night 
about midnight under CRON (1). I am having reliability/stability 
problems with this process, which I only began doing a few weeks ago 
(before that, I used 1 on my SGI Octanes for this task, but I had a HDD 
go out on it, so I switched to the 2.4 GHz P4). The directories from the 
other machines are mounted using AUTOMOUNT & NFS. I attach the syslog 
entries from last night's botched backup. Are there any known problems 
w/ automount/nfs under SuSE 9.2 or Linux more generally ? How about 
interacting w/ SGI's (2 of the boxes I am backing up are SGI's) ? 
Whenever I reboot, things go OK for 2 or 3 days, then screw up .... TIA 
& merry Christmas :-).
