I was working on partitioning on slice 5 and 6. After serveral to mount the new partition unsuccessfully, so I decide to reboot the machine to do fsck. The system never came back up and enter single user mode. I try use command but it l not execute, look like the filesystem is gone. I get "segmentation fault" error. Any advice to fix this.
Which filesystems were on slices 5 and 6? Also, after you modified the sizes of the slices, did you create new file systems before attempting to mount them? You may want to boot off of a CD and then fix the file systems if you need to.
Hey Stickman....the machine was running during partition. I was able to boot from cdrom and started to do fsck. The fsck run and notice alot of blocks need to fix, delete, remove, etc. I think I corrupt the whole disk. Anyway to fix this chaos? When i do a df -k, i notice filesystem like export, var are missing. When I mount, the disk is busy.
Working with a live file system is tricky, and I would not recommend doing anything like this unless you have some sort of volume management software in place. Also, it is a very rare day when Solaris will let you mount a file system that needs to be fsck'd. You'll need to fsck them first.
When you boot from CD and do a "df -k", you are seeing only the file systems on the CD unless you mount the drive slices. You'll need to mount the drive slices to /mnt or the system will give you the "busy" error.
