Hi, There is a difference between the help of lvresize and its man page. In the manpage, there is nothing about the -r or --resizefs function. Centos4. [root at serv01 ~]# lvresize Please specify either size or extents (not both) lvresize: Resize a logical volume lvresize [-A|--autobackup y|n] [--alloc AllocationPolicy] [-d|--debug] [-h|--help]

CFQ considers it seeky (*), BFQ doesn't. As a side effect BFQ does not always dispatch enough requests to correctly detect tagging. At the first seek you cannot tell if the process is going to bee seeky or not, and we have chosen to consider it sequential because it improved fairness in some sequential workloads (the CIC_SEEKY heuristic is used also to determine the idle_window length in

Hi, dear friend. My guest has two disks, vda and vdb. both are qcow2 local file. When guest running state. I want to take the vda snapshot of guest(just vda, no include vdb). but I met libvirt do snapshot for all disks of guest. About methods for follow: 1、 ``` bash virsh snapshot-create-as 8x0lbzvS --name sys_disk3 --disk-only --diskspec "vda,snapshot=external" ``` ``` result

hi, just wanted to mention that using 1.36-rc1 fixes the following bug: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=144771 thanks to benjamin scott for the hint, and theodore ts'o for fixing. building a source and binary rpm with the provided spec file works flawlessly under fc3 (just had to remove -rc1 from the archive name and Version: in the spec file). if you are replying to

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

And how would it help? If I shrink, a want a VM to occupy less maximum

Sometimes the user wants to know minimum size for dirty (e.g. mounted) filesystems. In this case, resize2fs -P will require calling e2fsck -f, while "in general, it is not safe to run e2fsck on mounted filesystems". Since resize2fs -P does not modify filesystem, we force it to display (probably approximate) minimum size. --- daemon/ext2.c | 2 +- 1 file changed, 1 insertion(+), 1

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

Hello, yesterday I experienced following problem with my ext3 filesystem: - I had ext3 filesystem of the size of a few TB with journal. I correctly unmounted it and it was marked clean. - I then ran fsck.etx3 -f on it and it did not find any problem. - After increasing size of its LVM volume by 1.5 TB I resized the filesystem by resize2fs lvm_volume and it finished without problem. - But

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

Tweak the error message "e2fsck -f" and "e2fsck -fy" to "e2fsck-f" and "e2fsck-fy".

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)"
