How can I mount a ufs filesystem on a solaris 10 sparc onto a Linux server

UNIX Solaris

Hi there,

I am trying to mount a SAN volume (which is mapped to solaris sparc) partitioned with ufs filesystem onto a linux (intel processor 64bit) server.

*I have re-compiled the linux kernel t support ufs fstype with ro mount support.

filesystem on solaris:
/dev/dsk/c2t2300000B080442C0d3s2
2.0G 2.1M 1.9G 1% /ilantry

fdisk -l o/p for the corresponding lun when mapped to linux:
Disk /dev/sdc (Sun disk label): 64 heads, 128 sectors, 2622 cylinders
Units = cylinders of 8192 * 512 bytes

Device Flag Start End Blocks Id System
/dev/sdc1 0 32 131072 2 SunOS root
/dev/sdc2 u 32 64 131072 3 SunOS swap
/dev/sdc3 u 0 2622 10739712 5 Whole disk
/dev/sdc7 64 2622 10477568 4 SunOS usr

Disk /dev/sdc1 (Sun disk label): 64 heads, 128 sectors, 2622 cylinders
Units = cylinders of 8192 * 512 bytes

Device Flag    Start       End    Blocks   Id  System

/dev/sdc1p1 0 32 131072 2 SunOS root
/dev/sdc1p2 u 32 64 131072 3 SunOS swap
/dev/sdc1p3 u 0 2622 10739712 5 Whole disk
/dev/sdc1p7 64 2622 10477568 4 SunOS usr

Disk /dev/sdc3 (Sun disk label): 64 heads, 128 sectors, 2622 cylinders
Units = cylinders of 8192 * 512 bytes

Device Flag    Start       End    Blocks   Id  System

/dev/sdc3p1 0 32 131072 2 SunOS root
/dev/sdc3p2 u 32 64 131072 3 SunOS swap
/dev/sdc3p3 u 0 2622 10739712 5 Whole disk
/dev/sdc3p7 64 2622 10477568 4 SunOS usr
-------------------

while try to mount it....
[root@pillar33 ~]# mount -t ufs -o ro,ufstype=sun /dev/sdc7 /lun1
mount: wrong fs type, bad option, bad superblock on /dev/sdc7,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

[root@pillar33 ~]# dmesg | tail

eth0: no IPv6 routers present
ufs: no version for "struct_module" found: kernel tainted.
ufs_read_super: bad magic number
[root@pillar33 ~]#

can somebody tell me how to get this working?

Thanks,

I doubt you can.
Linux supports mounting UFS created under the same endianness CPUs. I assume your Linux box is on x86 which is little endian while SPARC is big endian.

Yes jlliagre, my linux box is of x86_64. I read that with the difference in endianness we cannot mount sparc slices onto intel buut, I am still checking that if this is a dead end or is there a way to go about this!!

Thanks for the helpful information.

with these difference in endiannes?

Just a thought, if anybody know about these sort of trick, please post.
