[PATCH 0/4] Allow shrinking of ext2, PVs and NTFS
by Richard W.M. Jones 21 May '10

21 May '10

This patch series allows you to shrink various objects, as requested in the following bugs: https://bugzilla.redhat.com/show_bug.cgi?id=585221 # resize2fs https://bugzilla.redhat.com/show_bug.cgi?id=585222 # pvresize https://bugzilla.redhat.com/show_bug.cgi?id=585223 # ntfsresize The first patch provides a consistent way to specify numbers with suffixes to guestfish, eg: truncate-size /foo 1G It also unifies the number parsing code used by 'alloc' and 'sparse' commands to use the same Gnulib function. Patches 2-4 implement the resizing. With all four patches applied you can shrink filesystems even where the container is larger, and you can use suffixes to specify the new filesystem size. Example using resize2fs-size: $ guestfish -N fs:ext3:1G Welcome to guestfish, the libguestfs filesystem interactive shell for editing virtual machine filesystems. Type: 'help' for a list of commands 'man' to read the manual 'quit' to quit the shell ><fs> vfs-type /dev/vda1 ext3 ><fs> blockdev-getsize64 /dev/vda1 1073741312 ><fs> resize2fs-size /dev/vda1 100M ><fs> blockdev-getsize64 /dev/vda1 # container size same 1073741312 ><fs> mount-ro /dev/vda1 / # but filesystem is smaller ><fs> df-h Filesystem Size Used Avail Use% Mounted on /dev/vda1 98M 17M 77M 18% /sysroot Example using pvresize-size: $ guestfish -N part:1G Welcome to guestfish, the libguestfs filesystem interactive shell for editing virtual machine filesystems.

RHN support and capabilities
by Matthew Booth 19 May '10

19 May '10

This patch series includes a repost of Milan's unmodified RHN support patch because I haven't pushed it yet. On top of that patch, it includes the capabilities patch in as many bits as I could make it into. The big one is 7/8. I've tested all of the following guests both with and without RHN registration: Xen RHEL 54 PV Xen RHEL 51 PV Xen RHEL 48 PV ESX RHEL 54 FV
