    Hi

    I'm currently running a Fedora 22 kickstart install to one of our
    backup servers. Its been running for nearly a day now!

    The root partition is on ext4 but there is a btrfs file system on
    top of md raid6 that holds our user backups. Each users' files are
    rsycned to the btrfs filesystem and then a snapshot made, so there
    are many thousands of snapshots.

    Currently the install has been running for nearly a day (the main
    screen is full of dots). Behind the scenes the installer seems to be
    working its way through all the snapshots with messages like this in
    storage.log:

    05:11:42,844 INFO blivet: hiding device existing 9.1 TiB btrfs
    snapshot home_xxx/20130423-000501 (59677) with existing btrfs filesystem
    05:11:42,848 DEBUG blivet: existing RAID raid6 size == 9.1 TiB
    05:11:42,852 DEBUG blivet: existing RAID raid6 size == 9.1 TiB
    05:11:42,857 DEBUG blivet: BTRFSVolumeDevice.removeChild: kids:
    32903 ; name: btrfs.133 ;
    05:11:42,858 INFO blivet: removed btrfs snapshot
    home_xxx/20130423-000501 (id 59677) from device tree
    05:11:42,858 DEBUG blivet: lvm filter: adding
    home_xxx/20130423-000501 to the reject list
    05:11:43,540 DEBUG blivet: existing RAID raid6 size == 9.1 TiB

    In my kickstart file I have a (legacy) line which I use to make sure
    that there is no possibility of the install happening to the wrong
    device:
    ignoredisk --only-use=/dev/disk/by-id/ata-ST380815AS_9RA8ZRZK

    where ata-ST380815AS_9RA8ZRZK is the disk I want to install the
    operating system to.

    Is it possible that this is whats causing the slowness?

    I guess I could remove the ignoredisk line now since I use the by-id
    name to identify the disk to install to in the 'part' commands. I
    think we introduced 'ignoredisk' ages ago when we had to specify
    partitions by names like /dev/hda1 and I was caught out once when
    the disks were enumerated in a different order in the installer than
    in the previous operating system I was using and the install
    happened to the wrong device.

    I'm disinclined to interrupt the install at the moment, as it does
    seem to be making progress, but confirmation that removing the
    'ignoredisk' line would avoid the issue I described would be useful.

    Thanks
