Resize file systen UFS
 

Is there any way to resize UFS filesystem online (with mounted and working file system) or offline (with unmounted filesystem) and not to lose datas ?

Eg. Let's say I have /opt with 10 Gb capacity and I have 5 Gb unformated space. I'd like to add that 5 Gb to /opt not to lose datas on /opt
Is this possible under Solaris 10

Once I did that with ext3 fs with tool parted (not gparted). The only thing was to run fsck after all. And it had to be done offline.

Hi.

If the space is continuous on disk (i.e. you can add the 5GB directly on to the end of the 10GB /opt area), you can edit the partition layout in 'format', then do 'growfs -M /opt /dev/rdsk/cXtYdZsN' to grow the filesystem.

resizing filesystems
 

On Linux, if resizing an ext2 / ext3 / ext4 file system, the file system may be safely grown online (i.e. while mounted) using resize2fs. Shrinking requires umounting the file system first. For Solaris UFS, growfs does not require the file system to be unmounted.
