Hello everyone! I am working on resizing qcow2 images using virt-resize+liguestfs. E.g. I when shrinking a partition, I have to resize filesystem using resize2fs-size. The problem is that I cannot find out minimal partition size (aka resize2fs -P). The only way is calling "resize2fs-size 1K", wait for resize2fs to claim "resize2fs: New size smaller than minimum (510050)"

Hi All: I am trying to resize a centos (5.2) VM drive. I use VMware and I have increased the size of the drive by 40G. I am running resize2fs on /dev/sdb1 (which is my root partition) but when I do I get this error: [root at centos ~]# resize2fs /dev/sdb1 120G resize2fs 1.39 (29-May-2006) The containing partition (or device) is only 19970795 (4k) blocks. You requested a new size of 31457280

Consider this section: http://www.tldp.org/HOWTO/Software-RAID-HOWTO-4.html#ss4.14 I have not done this before and I'm leary about Step 11 which is resizing the filesystem after doing a mkraid command. This howto lacks any ext3 documentation. Some questions I have are: 1. Should I convert back to ext2 on all my filesystems before I do a mkraid? 2. If I leave the system at ext3, will the

Hullo! First mail, sorry if this is the wrong place for this kind of question. I realise this is a "piece of string" type question. tl;dr version: I have a resizefs shrinking an ext4 filesystem from ~4TB to ~3TB and it's been running for ~2 days. Is this normal? Strace shows lots of:- lseek(3, 42978250752, SEEK_SET) = 42978250752 read(3,

https://bugzilla.redhat.com/show_bug.cgi?id=755729 This bug reports that the error message printed by the resize2fs API calls (which comes directly from the resize2fs command) says: Please run 'e2fsck -f /dev/vda1' first. That command is not possible from guestfish (where it would be 'e2fsck-f' or 'e2fsck ... forceall:true'). Fixing that bug caused this bug:

Hi all, Can I ask if zerofree or resize2fs could also be applicable to ext4? Guestfish help of these two commands indicates that they are applicable to ext2/3. But ext4 is not covered in the help. However, I have tested these two commands in my Fedora 12 laptop, and it seems that both commands work well with ext4. So I don't quite understand why the help of these two commands only mention
