Special Forums Hardware Filesystems, Disks and Memory Is it possible to resize a slice under Solaris 8 Post 45921 by jsilva on Monday 5th of January 2004 07:15:11 PM

Hi,

You cannot "resize" a slice, but you can grow a filesystem ( it's not possible to shrink it again ! )... I assume that you don't have any volume manager installed... Advice: backup, backup, backup !

Is you have unallocated space beyond the slice you're extending, use /usr/lib/fs/ufs/mkfs -G -M /mountpoint /dev/rdsk/cxtxdxsx size .

Otherwise you can do it more safely this way:
umount filesystem ( if cannot be umounted, start in single user mode, using the CD ), backup the filesystem, resize the slice, create new filesystem, restore the backup onto this new filesystem, update /etc/vfstab, reboot...

Did i mention to backup ?... :-)

Good luck !

NAME
vgcfgbackup - backup volume group descriptor area SYNOPSIS
vgcfgbackup [-d|--debug] [-f|--file filename] [-h|--help] [--ignorelockingfailure] [-P|--partial] [-v|--verbose] [VolumeGroupName...] DESCRIPTION
vgcfgbackup allows you to backup the metadata of your volume groups. If you don't name any volume groups on the command line, all of them will be backed up. In a default installation, each volume group gets backed up into a separate file bearing the name of the volume group in the directory /etc/lvm/backup. You can write the backup to an alternative file using -f. In this case if you are backing up more than one volume group the filename is treated as a template, and %s gets replaced by the volume group name. NB. This DOESN'T backup user/system data in logical volume(s)! Backup /etc/lvm regularly too. OPTIONS
See lvm for common options. SEE ALSO
