filesystem-available should return false for xfs in rhel6
Last modified: 2013-11-20 23:45:32 EST
Description of problem: rhel6 does not support xfs, so libguestfs command "filesystem-available" should returns false Version-Release number of selected component (if applicable): libguestfs-1.20.9-6.el6.x86_64 How reproducible: 100% Steps to Reproduce: [root]# guestfish -N fs filesystem-available xfs true Actual results: return true Expected results: return false Additional info:
It's correct, isn't it? ><rescue> modprobe xfs [ 207.985415] SGI XFS with ACLs, security attributes, large block/inode numbers, no debug enabled [ 208.005215] SGI XFS Quota Management subsystem ><rescue> grep xfs /proc/filesystems xfs I also created an xfs filesystem on Fedora: fedora$ guestfish -N fs:xfs exit and then copied it (test1.img) over to RHEL 6: rhel6$ guestfish -a /tmp/test1.img Welcome to guestfish, the libguestfs filesystem interactive shell for editing virtual machine filesystems.

If this returns true, it doesn't mean that a particular filesystem can be mounted, since filesystems can fail for other reasons such as it being a later version of the filesystem, or having incompatible features. (We might change that to say "created or mounted").
I pushed this upstream: https://github.com/libguestfs/libguestfs/commit/280dbed9aabcb5aa2ddbed4f0c49a82235df7eae
Verified with libguestfs-1.20.10-2.el6.x86_64, ><fs> help filesystem-available NAME filesystem-available - check if filesystem is available SYNOPSIS filesystem-available filesystem DESCRIPTION Check whether libguestfs supports the named filesystem. The argument "filesystem" is a filesystem name, such as "ext3". You must call "launch" before using this command. This is mainly useful as a negative test. If this returns true, it doesn't mean that a particular filesystem can be created or mounted, since filesystems can fail for other reasons such as it being a later version of the filesystem, or having incompatible features, or lacking the right mkfs.<*fs*> tool. See also "available", "AVAILABILITY" in guestfs(3). ><fs> Document modified, so change the status to verified
