Hi,
The following is also in prettier form at http://www.lqx.net/~matt/
sparc-vserver
I have a few issues with vserver on sparc. Namely, permission denied
errors (which are pretty broad) when trying to su or when cron tries
to run a crontab (even a root crontab). Also, when stopping the
vserver with nfs points mounted, a kernel error is generated. The
former issues are #1 and #2 while the latter issue is #3.
Platform: Sun T2000 (8-core, 1ghz, 8GB RAM)
Kernel: Linux 2.6.19-vs2.3.0.6-gentoo #3 SMP Mon Jan 22 19:09:52 MST
2007 sparc64 sun4v UltraSparc T1 (Niagara) GNU/Linux
Installed Versions:
sys-libs/glibc-2.3.6-r5 USE="nptl nptlonly -build -erandom -glibc-
compat20 -glibc-omitfp (-hardened) (-multilib) -nls -profile (-
selinux)" 0 kB
dev-libs/dietlibc-0.30-r2 USE="-debug" 0 kB
sys-cluster/util-vserver-0.30.212-r1 USE="-bash-completion" 0 kB
Issue #1:
In the vserver, the cron daemon starts but is unable to run any
crontabs. The result of it trying is:
Jan 23 13:00:01 cron[15618]: Permission denied
in /var/log/messages. This is certainly related to issue #2.
Issue #2:
In the vserver, su is unable to change to any user. Doing so results
in the following error
su: Permission denied
The following is shown in /var/log/messages:
Jan 23 13:26:27 su[6123]: Successful su for dude by root
Jan 23 13:26:27 su[6123]: + pts/2 root:dude
Jan 23 13:26:27 su(pam_unix)[6123]: session opened for user dude by
(uid=0)
Jan 23 13:26:27 su[6123]: pam_open_session: Permission denied
A log of strace for su - can be found at http://www.lqx.net/~matt/
sparc-vserver/su.log
Issue #3:
The vserver is unable to be shutdown cleanly due to mounted nfs
mounts. Stopping the vserver produces this error message:
/usr/lib/util-vserver/vserver.functions: line 895: 8230 Segmentation
fault $_VWAIT --timeout "$VSHELPER_SYNC_TIMEOUT" --status-fd 3
"$2" >>$_is_tmpdir/out 2>$_is_tmpdir/err 3>$_is_tmpdir/fifo
internal error: 'vwait' exited with an unexpected status ''; I will
try to continue but be prepared for unexpected events.
and this in the kernel messages:

[ 1071.770209] Fixing recursive fault but reboot is needed!
After this point, as it says, a reboot is needed. The vserver fails
to start again. With no nfs shares mounted, the vserver shutdown
cleanly.
Any help is appreciated..
