Hi Guys,
I just tried to reboot my server, but it seems to be panicing and unable to mount the root disk.
The filesystem is supposed to be ufs, so im not sure why its talking about vfs.
At the moment it's just stuck in a loop of Reboot-panic-reboot.
Hallo together,
I have a litle problem with some of my external devices.
If I type mount there are some "panic" massages.
Is this a real mistake or is this a normal behavior of a Solaris 8 system ?

Presently I have mounted a disk as su. I believe only root can mount disks -- is this correct?
I had to run mozilla in the root account so I can download the new SuSE distribution to the new disk.
How can I mount the disk so non-root accounts can access the disk?
Thanks,

I have a USB disk on a little NAS controller (NSLU2 running unslung 6.8) that I can access nicely with root with

I have a Debian OpenBox that boots from any usb port. The Debian LXDE will only boot from one specific port. It needs to look at all of them to find and be root, and mount the root filesystem by UUID. Both are full installs to 16GB flash drives.
That is not being done.

LEARN ABOUT ULTRIX
mount
mount(8ufs)mount(8ufs)Name
mount - mount the local ULTRIX File System (UFS)
Syntax
/etc/mount [ -t ufs -r ] [ options ] device directory
Description
The command announces to the system that a file system is present on the device device. The specified device must be a local device. The
file directory must exist and it must be a directory. It becomes the name of the newly mounted file system.
To further protect from system crashes, only file systems that have been cleanly checked by are mounted. In emergency situations, the
superuser can override this requirement by using the option as shown below.
General users can mount file systems with certain restrictions in addition to those listed in The file system must have the clean byte set.
To ensure the clean byte is set, run the command on the file system first. You can also try the mount and if it fails, then run and then
try the mount again.
Note that the user must have execute permissions on the device.
A successful ufs-mount may generate the following warning message:
"Warning, device has exceeded xxx threshold, fsck(8) is advised"
where xxx is which metric was exceeded to cause the clean byte timeout factor to reach zero. See for an explanation of the timeout algo-
rithm.
Physically write-protected disks and magnetic tape file systems must be mounted read only or an error will occur at mount time.
Options
See the reference page for a description of the -t option.
-o options Specifies options as a sequence of comma-separated words from the list below.
force The superuser can force the mounting of unclean file systems. You should use the flag only in single-user mode
when repairing or recovering damaged file systems.
nodev Block and character special devices cannot be accessed from this file system. If you are concerned with nfs secu-
rity, all ufs file systems that will be exported via nfs should be ufs mounted with the option.
noexec Binaries cannot be executed from this file system.
nosuid The and programs may not be executed from this file system. If you are concerned with nfs security, all ufs file
systems that will be exported via nfs with the option specified in the file should be ufs mounted with the nosuid
option.
pgthresh=## Set the paging threshold for this file system in kilobytes. The default is 64 kilobytes.
sync All writes are immediately written to disk (synchronously) as well as to the buffer cache. For the option to be
meaningful, the file system must be mounted with write permissions.
-r Mounts the device on directory read only.
Restrictions
The command should only be invoked by the command. Users (and superusers) should not invoke the command.
Examples
The command calls to do its work and is the preferred interface. A sample command is:
# mount -t ufs -o nodev,nosuid,noexec,pgthresh=100 /dev/ra0g /usr
