Strange behavior of zone after reboot
Hi All,

I have Solaris-10 M4000 server with VxVM file-system and 7 zones. I rebooted the server and after that one of the zone shows me in running state, but after zlogin, it is showing no df and other output. It is also throwing lot of core dumps
Code:
# uname -a

On Global server :-
Code:
  ID NAME             STATUS     PATH                           BRAND    IP
   0 global           running    /                              native   shared
   1 tssoaq01-zwfsr01 running    /zone/tssoaq01-zwfsr01         native   shared
   2 tssoaq01-zwpsq01 running    /zone/tssoaq01-zwpsq01         native   shared
   3 tssoaq01-zwpsr01 running    /zone/tssoaq01-zwpsr01         native   shared
   4 tssoaq01-zwfsq01 running    /zone/tssoaq01-zwfsq01         native   shared
   5 tssoaq01-zwfsq02 running    /zone/tssoaq01-zwfsq02         native   shared
   7 tssoaq01-zwfsr02 running    /zone/tssoaq01-zwfsr02         native   shared
   8 tssoaq01-ztbgps17 running    /zone/tssoaq01-ztbgps17        native   excl

Affected zone is tssoaq01-ztbgps17. Can somebody give a clue ? Reboot of zone and even physical server didn't helped.

check the configuration of the zone... the filesystem mount points for the zone should be the problem.

Zonepath or mount points are not the problem. I ran fsck and they are clean. I can login to zone and can see the size of directories, but commands are working wiered
Code:
# touch /var/adm/test
Bad System Call - core dumped
# ls -l /var/adm/test
-rw-r--r--   1 root     root           0 Sep 25 11:06 /var/adm/test
# df -h .
df: Could not find mount point for .
# df -h /
df: Could not find mount point for /

You can check from the global zone what filesystems are mounted in that zone.

Code:
 
df -Z | grep <zonename>

Also, can you check the services output in that zone, whether all the services are ok or not.

Code:
 
svcs -xv

Vishal

Hi Vishal,

Correct file-systems are entered in zonezfg.

Services are also up inside zone, except few ones which are not relevent. But I do not know, what is this "Not owner" in my output. Don't know, if this is relevent.
Code:
root@tssoaq01:/zone/tssoaq01-zwpsq01/root/wps/env/profiles/WPSSimms01# ls -l
./tranlog: Not owner
total 28
drwxrwxr-x   3 wpsadmin 512

These not owner entries are for tssoaq01-zwpsq01 zone, so no worries, the zone in question is tssoaq01-ztbgps17.

df: cannot statvfs /zone/tssoaq01-zwpsq01/root/ddoa-events: Not owner
df: cannot statvfs /zone/tssoaq01-zwpsq01/root/wps/env/profiles/WPSSimms01/tranlog: Not owner
df: cannot statvfs /zone/tssoaq01-zwpsr01/root/wps/env/profiles/WPSSimms01/tranlog: Not owner

I get these "not owner" with df -Z when I have nfs mounts in a zone.

But it is clear that you don't have any lofs mount in your zone, there is some problem.

Can you try a manual lofs mount to this zone and see what it does.

Code:
mount -F lofs /zone/tssoaq01-ztbgps17/tbg /zone/tssoaq01-ztbgps17/root/tbg

Vishal
