What's that output > supposed to mean ? Is it a bug ? It isn't an error to scan a partition that doesn't have btrfs on it. btrfsctl -A is just a single shot scan of a single device. It is meant for use by programs like udev to scan storage. It think what you want is btrfs-show. -chris -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

Is it normal such issues are not tracked in the project's bugzilla: http://oss.oracle.com/bugzilla/buglist.cgi?product=Btrfs which only contains 5 bugs ?! I suppose it depends on whether its a bug with something that's supposed to work or whether its a feature that's not quite implemented yet. I think in this case, btrfsctl is providing some basic capabilities to assist development and testing and is quite likely to evolve, so to me this wasn't a bugzilla item. Chris might have different advice though. -- ljk On Fri, Jul 18, 2008 at 8:50 PM, Linda Knippers <[EMAIL PROTECTED]> wrote: Ahmed Kamal wrote: [EMAIL PROTECTED] progs-unstable]# btrfsctl -A /dev/sdb ioctl returns 0 [EMAIL PROTECTED] progs-unstable]# btrfsctl -A /dev/sdc ioctl returns 0 /dev/sdb has a btrfs, while /dev/sdc is blank.

If you look in /var/log/messages or where every your kernel messages go, you'll see information about the file system on the device. At least that's how it worked for me. -- ljk -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
