we have a server runnning solaris 10 (sparc)
this server is attached the a SAN (HP EVA)
we created 23 LUN's and filled them with data.
the we unmounted them and tried to attach the LUN's to a solaris 8 system.
this is where thing get strange...
when we just mount the LUN's it works fine, the data looks to be all good.
after this we updated the vfstab and re-booted.
at boot the OS had issues with the super block.
see errors below.
when we fsck the file system it repairs the super block and marks it as clean.
we still have the same problem at next re-boot.
errors:

If you are going to have to share this filesystem between a Solaris 8 and a Solaris 10 host then you will probably need to use something like VXFS, but the cheaper solution would be to make both hosts Solaris 10.
I wonder if the LUNs are not being unmounted cleanly on reboot. Perhaps some processes were still using them. I also wonder why s2 is being referenced, are you mounting the whole disk?
I have a Solaris 10 LDOM installed with UFS and another Solaris 11 LDOM with ZFS. I want to mount a folder on Solaris 10 to Solaris 11. I used the following:
sudo mount -F ufs 10.1.1.44:/export/home/amandeep/workspace /home/amandeep/workspace/mounts/ldom5
and it errors out with:

I'm prompted to start this thread following my attempt to help on this thread here (see my posts).
I was proposing the OP deep checked a Solaris ufs filesystem using:
# fsck -o full <filesystem node>
however this option does not appear to be valid on Solaris 10.

Hi folks
There are about 200 csh scripts (I didn't wrote them). Do all those scripts run with tcsh without modification? Is tcsh 100% compatible with the plain-old csh?

Hello,
For a company I have to check if it is possible to migrate there environment from a solaris 8 to solaris 10.
Is there a tool with which I can check if the libraries running now on the 8 are compatible with the 10?
Kind regards (3 Replies)
Hi, I'm new to BSD and would like to create a dual-boot between Solaris Express Community Edition and FreeBSD.
I would just like to know if the Solaris UFS file system can be written to by BSD?
I know that BSD uses UFS2, but I'm hoping that it is backwards compatible with UFS1 provided that... (0 Replies)
Hi,
Please can someone recommend me a cheap PCI Network card for Solaris 9 (9/05) for an Intel based PC (x86).
