We have an E450 with 2 disks (c0t0d0 & c2t0d0) and all the file systems are mirrored using Solaris Volume Manager with logging turned on. To upgrade the OS, we detach the c2t0d0 submirrors, perform a Live Upgrade (LU) and luactivate the new BE. We have performed the above process multiple times without issues. After we boot into the new BE there is a necessity to mount the old BE file systems for reference purposes. Sometimes when we mount the regular slices (/dev/dsk/c0t0d0s*) it panics the system with "UFS panic free: freeing free block" message.
Here are my questions: * Are we doing something illegal when we mount the regular slices (/dev/dsk/c0t0d0s*)? * Are the file system getting corrupted because of the metadevice and logging layers? * If the file system is corrupted, why isn't mount capturing the corruption? * How would I access the old BE file systems (which are under Solaris Volume Manger control) from my new BE? Thanks in advance. This message posted from opensolaris.org _______________________________________________ ufs-discuss mailing list [email protected]
