Yes, well that proves that the LUN is intact and perfectly readable.
Only you will know what these slices are. You should have the relevant filesystem locations documented. However, yes, slice 6 is the largest and certainly looks relevant so I would attempt to 'fsck' that device:
As always use the -n (no changes to be made) switch initially to explore what damage, if any, there is. If you only get a few problems flagged then run again without the -n and correct them when asked.
Hi All,
Thanks for taking the time to read and respond to my post.

I have upgraded my Solaris 10 2005 to Solaris 10 2007. I am facing one bug, id: 6550904. To override this issue I have done following changes in /etc/systems:
set max_uheap_lpsize = 0x2000
set max_ustack_lpsize = 0x2000
set max_privmap_lpsize = 0x2000

I'm moving an application from an old RS6000 running 4.3.2 to a p5 running 5.3.
Could someone point me a the direction on docs to perform such a function? Critical OS files, moving of printers and print queues especially.

I currently have a web server its on a small harddrive I didn't know my site would grow so fast but now I need a bigger hard drive.

Hi Everyone,
I'm still learning daily about UNIX (specifically Solaris 10).
I'm tasked with moving my current application and database from Datacenter A to Datacenter B.
There will be no updates and no changes other than a new server and new location.
So far, I have Solaris... (3 Replies)
I have a Perl script that worked fine before moving it to justhost.com. It was on a Windows/Apache server. Just host is using UNIX. Other Perl scripts on other sites that were also moved work fine so I know Perl is functioning.
The script is called cwrmail.pl and is located in my cgi-bin.

Hi all,
We have a disk array that has the boot drive on an OCZ SSD on a PCIe card. Well, the motherboard died and we got a new motherboard. We moved the controllers, NICs, etc, to the exact same slots on the new motherboard, except now it won't boot. I guess it doesn't recognize the OS on the... (1 Reply)

fsck.gfs2
fsck.gfs2(8) System Manager's Manual fsck.gfs2(8)NAME
fsck.gfs2 - Offline GFS and GFS2 file system checker
SYNOPSIS
fsck.gfs2 [OPTION]... DEVICE
WARNING
All computers must have the filesystem unmounted before running fsck.gfs2. Failure to unmount from all nodes in a cluster will likely
result in filesystem corruption.
DESCRIPTION
fsck.gfs2 will check that the GFS or GFS2 file system on a device is structurally valid. It should not be run on a mounted file system.
If file system corruption is detected, it will attempt to repair the file system. There is a limit to what fsck.gfs2 can do. If important
file system structures are destroyed, such that the checker cannot determine what the repairs should be, reparations could fail.
GFS2 is a journaled file system, and as such should be able to repair damage to the file system on its own. However, faulty hardware has
the ability to write incomplete blocks to a file system thereby causing corruption that GFS2 cannot fix. The first step to ensuring a
healthy file system is the selection of reliable hardware (i.e. storage systems that will write complete blocks - even in the event of
power failure).
Note: Most file system checkers will not check the file system if it is "clean" (i.e. unmounted since the last use). The fsck.gfs program
behaves differently because the storage may be shared among several nodes in a cluster, and therefore problems may have been introduced on
a different computer. Therefore, fsck.gfs2 will always check the file system unless the -p (preen) option is used, in which case it fol-
lows special rules (see below).
OPTIONS -a Same as the -p (preen) option.
-f Force checking even if the file system seems clean.
-h Help.
This prints out the proper command line usage syntax.
-q Quiet.
-n No to all questions.
By specifying this option, fsck.gfs2 will only show the changes that would be made, but not make any changes to the filesystem.
-p Preen (same as -a: automatically repair the file system if it is dirty, and safe to do so, otherwise exit.)
Note: If the file system has locking protocol lock_nolock, the file system is considered a non-shared storage device and the fsck is
deemed safe. However, fsck.gfs2 does not know whether it was called automatically from the init process, due to options in the
/etc/fstab file. Therefore, if the locking protocol is lock_dlm and -a or -p was specified, fsck.gfs2 cannot determine whether the
disk is mounted by other nodes in the cluster. Therefore, the fsck is deemed to be unsafe and a warning is given if any damage or
dirty journals are found. In that case, the file system should be unmounted from all nodes in the cluster and fsck.gfs2 should be
run manually without the -a or -p options.
-V Version.
Print out the program version information.
-v Verbose operation.
Print more information while running.
-y Yes to all questions.
By specifying this option, fsck.gfs2 will not prompt before making changes.
