filesystems resizing

[Ling709]

I want to resize my filesystem partitions. Reason is that I have 11GB of disk space unused by Unix which divvy reveals. Is there a way I could resize my filesystems without doing a reinstallation. The secondary problem is that the boot image is too large for a diskette (5MB).



I'm running SCO Openserver 5.0.6, RAID 5



I'll appreciate your assistance. Thanks

More Information:

1. It appears that Knoppix does not automatically mount the LVM filesystems, nor have them as block devices in the /dev directory
2. I'd like to know if resizing ext3 filesystems is supposed to be > supported while online
3. Looks like the partition resizing worked, but not the filesystem resizing
4. A method for supporting resizing of file system partitions within a storage system, the storage system being divided into a plurality of partitions, each
5. See the following manual pages for more information about resizing file systems:
6. Valid filesystems: “Case-sensitive HFS+” “Journaled HFS+” “Case-sensitive Journaled HFS+” “HFS+” “HFS” “MS-DOS FAT32” “MS-DOS FAT16” “MS-DOS” “MS-DOS
7. The resize2fs program doesn't resize partitions, just the filesystems they contain

First of all, if you are talking about /var, /, /usr, /tmp, /opt, or any other primary UNIX filesystem you will have to do your work from single user mode. Unless you have a product like Vertas Volume manager and Filesystem manager that will allow you to do changes online.



Second, If you are trying to reduce these filesystems, you will need to make a backup copy first just for safety's sake.



If you go to single user and reduce your filesystems. Make sure that the disk(s) you are removing have NO DATA on them. query your disks to see if they do or not.



If your disks have data on them that you want to remove. Make a backup copy and then reduce the filesystem then restore.



Of course if you have a product like Veritas, you can do this online for all except the root filesystem, I believe.

1. 6 posts - 4 authors - Last post: Feb 8Could someone of the developers provide me with any informations regarding support to resizing the GPFS disks/LUNs?
2. There have been various bugs in gparted relating to resizing filesystems
3. from the LVM package, or for ease-of-use you can use e2fsadm(8) which combines the LV extension and ext2 filesystem resizing into one step
4. Several reports of problems resizing file systems using GParted have been posted by users in this forum
5. The ext2online tool can currently only resize ext3 filesystems online, despite references to ext2 filesystems in this manpage
6. Make sure all of your other filesystems on /oldroot, such as /oldroot/sys etc, have been unmounted first
7. Alongside it, there exists another tool - resize2fs which is capable of ext2/ext3 filesystem resizing
8. at editing NTFS filesystems it doesn't understand, but that's yet another reason why proceeding without tested backups is risky
9. Conventional wisdom on the subject of growing seems to have said that after resizing your virtual disk, you had to reboot to see the extra space
10. Thus, the embodiments of the invention enable dynamic resizing of file systems within a group by borrowing data blocks from one or more file systems

Thnaks for the interest. I have only 3 fs. root, swap and user. Root is 93% full meanwhile I have 11GB of disk space not utilised by unix or any other OS. I want to simply increase the root fs and users to use the 11GB space.

Increase root with 2GB more and users with the remaining space.



Thanks.

7. The ext2resize tool is for resizing unmounted filesystems, and ext2online is for growing a mounted filesystem (it needs a kernel patch to work, however
