Mount Solaris partition in FC7

zillah · 11-24-2007, 08:54 PM

I have got three OSs (Windos2003, Solaris Express CE, FC7) , I am looking to mount solrais partition through FC7

This what I had done :
[root@localhost mnt]# mkdir /mnt/SOL
[root@localhost mnt]# cat /etc/fstab

Code:

LABEL=/                 /                       ext3    defaults        1 1
LABEL=/boot             /boot                   ext3    defaults        1 2
tmpfs                   /dev/shm                tmpfs   defaults        0 0
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                   /sys                    sysfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
LABEL=/home             /home                   ext3    defaults        1 2
/dev/sda3               swap                    swap    defaults        0 0
LABEL=SWAP-sda8         swap                    swap    defaults        0 0
/dev/sda1            /mnt/W2K3   ntfs    ro,defaults,umask=0222         0

Code:

[root@localhost ~]# fdisk -l

I tried below but they did not work
[root@localhost SOL]# mount -oufstype=sunx86 /dev/sda3 /mnt/sol

[root@localhost SOL]# mount -o ro -t ufs /dev/sda3 /mnt/SOL
mount: /dev/sda3 already mounted or /mnt/SOL busy

Your fstab is mounting the Solaris partition as Linux swap ...

!!

This is a good way to destroy your Solaris installation.

Moreover, you try to mount that primary partition while you should instead mount ufs slices.

You need to check also if ufs support is there in your distribution. Have a look at the O/S boot messages (dmesg) to see if the slices are detected by the Linux kernel.

I'm surprised it even mounted as swap. What does "swapon -s" display; whilst you're in dmseg, have a look for any swap related messages as well.

Because when I created the partition where solaris resides now, as type of :" swap ".

syg00 · 11-25-2007, 01:45 AM

Whoa !!!.
O.K., delete the line for /dev/sda3 (for swap) out of fstab, and do a "swapoff /dev/sda3" from your (running) Linux system.
After that, it's over to jlliagre for advice regarding Solaris

Are you saying that the new code for /etc/fstab should like similar ro below ?

Code:

LABEL=/                 /                       ext3    defaults        1 1
LABEL=/boot             /boot                   ext3    defaults        1 2
tmpfs                   /dev/shm                tmpfs   defaults        0 0
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                   /sys                    sysfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
LABEL=/home             /home                   ext3    defaults        1 2

 
LABEL=SWAP-sda8         swap                    swap    defaults        0 0
/dev/sda1            /mnt/W2K3   ntfs    ro,defaults,umask=0222         0

syg00 · 11-25-2007, 02:03 AM

Yep - looks o.k.

jlliagre · 11-25-2007, 02:19 AM

I hope swapoff isn't going to do destructive actions.

Anyway, you should then try to mount sda9 (s0) and sda12 (s7) which are likely Solaris "/" and "/export".

Before doing this

Could you please let me know what the exact command for mounting sda9 (s0) and sda12 (s7) which are likely Solaris "/" and "/export". I just want to give a try and see

jlliagre · 11-25-2007, 02:50 AM

Something like (I haven't a machine to check right now):

Code:

mount -t -ufs -o ufstype=sun,ro /dev/sda9 /mnt/solaris

Has happened at every shutdown, so I can't see any (further) damage eventuating. Merely causes swapped-out (physical rather than swap-cache) pages to be swapped back into storage, and the swap extent freed.

Looks like it's unused anyway - at least when that display was done.

jlliagre · 11-25-2007, 03:30 AM

Yes. I would be interested to know why the Solaris partition was set as swap in the first place. This used to be an issue with older versions when the Solaris partition id (0x82) was clashing with Linux swap.

Now Solaris id is 0xbf so there is no reason for this confusion to appear outside user mistake or Linux distribution hostile behavior ... I hope what happened is the former guess.

zillah · 11-25-2007, 03:59 AM

Without changing the /etc/fstab, and without using swapoff command, I was able to mount. This is what i have done:

Code:

[root@localhost ~]# mount -o ro -t ufs /dev/sda9 /mnt/SOL
[root@localhost ~]# cd /mnt/SOL
[root@localhost SOL]# ls
bin   devices  home    lost+found  net       proc    tmp
boot  etc      kernel  media       opt       sbin    usr
dev   export   lib     mnt         platform  system  var
