Add SWAP to free slice

I'm interested in adding more swap space to my current workstation (Solaris 10). I currently have 2 hard drives installed, however the system was only created with 512MB for swap that resides on drive 1. This drive is already sliced up and all slices are being used.

The second drive has two slices (50G & 25G), however only the 50GB slice is being used. Is there a way I can slice the 25GB into two slices and use one of the new slices for swap? I have data on the 50G slice that I can't afford to lose.

I realize that more swap can be added by simply creating a file and using that as swap, but I'd rather using a partition (if possible) since I have it available.

In addition (for my future reference), are swap related errors written to /var/adm/messages? I looked in this file and it ONLY had two lines that were dated two days ago. These entries were unrelated to swap. Is this file purged on reboot? The workstation has been active for 6-months now and there were only 2 lines in this file.

Thanks.

Hi Gurus, For a particular slice I have change the minfree from 10% to 1% with tunefs -m and its allowing the creation of file on that slice, however when I am seeing the same with df -k it says that the slice is 100% full. What could be reason for this? Thanks (2 Replies)

volrootmir(8)						      System Manager's Manual						     volrootmir(8)

NAME
volrootmir - Mirror areas necessary for booting to a new disk SYNOPSIS
/usr/sbin/volrootmir [-a] [nconfig=count] target_disk [swap=target_partition] OPTIONS
Specifies that all volumes on the system disk be mirrored, not just the root and swap volumes, rootvol and swapvol. DESCRIPTION
The volrootmir script causes a mirror copy of areas of the root disk involved in booting to be made on the specified target disk. When used without the -a option, volrootmir adds mirrors of the root and swap volumes and allocates them on the new disk. In addition, all disk regions required for booting are set up and partitions for the new volume mirrors are created. When used with the -a option, volrootmir mirrors all in-use partitions on the system disk. To mirror a swap volume that is on a separate disk from the root volume, the swap attribute must be used to specify a separate target for the swap mirror. The target disk(s) must be at least as large as the sum of the sizes of rootvol and swapvol. Also, the physical disk should not have any disk partition in use. This script can be called from the voldiskadm menus by choosing the Mirror volumes on a disk operation. ATTRIBUTES
Specifies the number of log copies and copies of the configuration database, for example, nconfig=2. Specifies that the swap volume, swapvol, be mirrored on a separate disk, as specified by target_partition. EXAMPLES
The following command mirrors the rootvol and swapvol volumes onto the target disk, dsk3. This command will fail if swapvol is on a differ- ent disk from rootvol. # volrootmir dsk3 The following command mirrors rootvol, swapvol, and any other volumes on the root disk onto the target disk, dsk3. This command will fail if swapvol is on a different disk from rootvol. # volrootmir -a dsk3 The following command mirrors rootvol on disk dsk3, swapvol onto partition dsk7d, and any other volumes on the root disk onto disk dsk3. This command will fail if swapvol is on the same disk as rootvol. # volrootmir -a dsk3 swap=dsk7d The following command mirrors rootvol onto disk dsk3 and swapvol onto partition dsk7d. This command will fail if swapvol is on the same disk as rootvol. # volrootmir dsk3 swap=dsk7d SEE ALSO
