Oh, just to let you know, the OS is based on Linux kernel 2.6 GPL Linux.
The system (NAS) was running for about a year before this happened.
I came across one thread on another website that another person having a similar problem was suggested to try vgscan from the lvm2 package, I'm not sure what that is, but thought I'd add it.
I am running mandrake 8.2 and when booting I get the message:

The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and really contains a valid an ext2 filesystem (and... (1 Reply)
Hi,
when installing a piece of third part software I get the error "Bad magic number" at one point when it tries to use libraries from the bea tuxedo server. Am I correct that this means that the software is expecting 32bit while I'm on 64bit? Is there a way around it or can it only be solved... (5 Replies)

Hello All,

Few weeks ago I had posted a message in this forum about the problem I had when I replaced my two scsi disks and tried rebuild raid1 array.
I somehow managed to up the system with working raid1 array.
But the main problem persisted..
i.e when I reboot the system, mounting... (0 Replies)

I'll keep it fairly straight forward. I work with a Solaris server and magically today it decided to take a dump on me.

So we have a new to us v240 server with no OS installed. It has an outdated version of OB and ALOM so before we install the OS we want to update both. We have a DVD with the latest OB patch burned on it.

partx
PARTX(8) System Administration PARTX(8)NAME
partx - tell the kernel about the presence and numbering of on-disk partitions
SYNOPSIS
partx [-a|-d|-P|-r|-s|-u] [-t type] [-n M:N] [-] disk
partx [-a|-d|-P|-r|-s|-u] [-t type] partition [disk]
DESCRIPTION
Given a device or disk-image, partx tries to parse the partition table and list its contents. It can also tell the kernel to add or remove
partitions from its bookkeeping.
The disk argument is optional when a partition argument is provided. To force scanning a partition as if it were a whole disk (for example
to list nested subpartitions), use the argument "-" (hyphen-minus). For example:
partx --show - /dev/sda3
This will see sda3 as a whole-disk rather than as a partition.
partx is not an fdisk program - adding and removing partitions does not change the disk, it just tells the kernel about the presence and
numbering of on-disk partitions.
OPTIONS -a, --add
Add the specified partitions, or read the disk and add all partitions.
-b, --bytes
Print the SIZE column in bytes rather than in human-readable format.
-d, --delete
Delete the specified partitions or all partitions.
-g, --noheadings
Do not print a header line with --show or --raw.
-l, --list
List the partitions. Note that all numbers are in 512-byte sectors. This output format is DEPRECATED in favour of --show. Do not
use it in newly written scripts.
-n, --nr M:N
Specify the range of partitions. For backward compatibility also the format M-N is supported. The range may contain negative num-
bers, for example --nr -1:-1 means the last partition, and --nr -2:-1 means the last two partitions. Supported range specifications
are:
M Specifies just one partition (e.g. --nr 3).
M: Specifies the lower limit only (e.g. --nr 2:).
:N Specifies the upper limit only (e.g. --nr :4).
M:N Specifies the lower and upper limits (e.g. --nr 2:4).
-o, --output list
Define the output columns to use for --show, --pairs and --raw output. If no output arrangement is specified, then a default set is
used. Use --help to get list of all supported columns. This option cannot be combined with the --add, --delete, --update or --list
options.
-P, --pairs
List the partitions using the KEY="value" format.
-r, --raw
List the partitions using the raw output format.
-s, --show
List the partitions. The output columns can be selected and rearranged with the --output option. All numbers (except SIZE) are in
512-byte sectors.
-t, --type type
Specify the partition table type.
--list-types
List supported partition types and exit.
-u, --update
Update the specified partitions.
-S, --sector-size size
Overwrite default sector size.
-v, --verbose
Verbose mode.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
EXAMPLES
partx --show /dev/sdb3
partx --show --nr 3 /dev/sdb
partx --show /dev/sdb3 /dev/sdb
All three commands list partition 3 of /dev/sdb.
partx --show - /dev/sdb3
Lists all subpartitions on /dev/sdb3 (the device is used as whole-disk).
partx -o START -g --nr 5 /dev/sdb
Prints the start sector of partition 5 on /dev/sdb without header.
partx -o SECTORS,SIZE /dev/sda5 /dev/sda
Lists the length in sectors and human-readable size of partition 5 on /dev/sda.
partx --add --nr 3:5 /dev/sdd
Adds all available partitions from 3 to 5 (inclusive) on /dev/sdd.
partx -d --nr :-1 /dev/sdd
Removes the last partition on /dev/sdd.
