Hello all,
I'm ufs file system, how can u use the same disk in another machine with the data in tact? to make it clear, I've an ufs FS in a mount point /file1 ( 8GB). now they decide to reintall the OS. After the reinstall, how can i get the same data as it is? will mounting the disk as /file1 give me back all the data? so id there some other thing that i need to take care.?

If the partition(s) on the disk is not changed/formatted then you should be able to use it in the other system with no problems.

If the disk is a total of 8GB and it's all in the one partition (excluding any small partitions possibly used for volume management) then moving the disk is simple.

If you are using a volume manager, like Vertias or DiskSuite, then you have some reading to do on removing (exporting) the partition to the new server.

Please post if you are using any volume management software and the layout (partitions) of the disk being moved. Also the OS version of the system the disk is in and the one it's going to.

Since you are using ufs I doubt you are using any type of volume manager like veritas. The one thing you need to be aware of is that the device may have changed between systems depending on the controller you attached it to. For example, on system1 it may have been c0t1d1 but on system2 it could be c1t1d1 or something else. You just need to be aware of this when you try to mount it on system2.

so that means that all i need to do is to identify the device file of the new disk and then make an entry in vfstab with same os differnet mount point...and i get back the data...Correct me if i'm wrong..tony answer makes it very clear if there is only file system. What if i've say more than one ....the corresponding entry in vfstab get me the data? guess i'll right?
