hello, I'm relatively new to unix and have just installed solaris 10 on a server. However, after installing some additional packages and configuring the system I realized the root drive partition is too small (i need to double it). Is there a tool to repartition the drive without having to reinstall everything?
Many thanks for any help,
Mark
Not that I'm aware of. Unfortunately you're stuck if they are physical slices.
I haven't played with parted or partition magic on solaris/ufs partitions.
Going forward, you could try this out -- have one large slice for rootfs and then encapsulate it with Sun Volume Manager. Then you can create soft slices on this metadevice, mount them as your various filesystems -- thus breaking free of the 7-slice (physical) limit of Solaris.
Try these steps:
1. Find the partition with the most available space. I will use /usr for my example
#df -k
2. Find the directory on root which takes up the most space. Hopefully it is not a core directory. I will use /opt for my example
# cd /
# du -sk *
3. move that directory to the partition with the most space. ( you shoud first verify that it has enough space to hold it)
#mv /opt /usr/opt_moved_from_root
4. Link the directory back to "/"
# ln -s /usr/opt_moved_from_root /opt
cg
no need -
try this instead -
df -n
Assuming you don't have a situation where /proc is not a mounted filesystem, you'll note /proc isn't ufs, it's proc for filesystem type and as such has no bearing on your root filesystem's space.
btw - i'm hoping in the previous post, they're not asking you to move and sym link a directory such as /usr or /opt on the fly. /opt - depending on what's installed there, may work, /usr will cause you to boot to cdrom and fix
if you want to grow the root filesystem, you'll need a space to store the old data that you'll need to backup/restore (typically on a spare disk), then you can ufsdump/tar/cpio/other the filesystem from current to new, and then in the case of the root filesystem, run installboot (check man -s 1m installboot)
too many ways to do this, please somebody provide a link to a previous post....
