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 majordomo@vger.kernel.org > 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 majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
Thanks Linda, I located the kernel message. 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 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 <linda.knippers@hp.com> wrote: >> Ahmed Kamal wrote: >>> [root@btrfs progs-unstable]# btrfsctl -A /dev/sdb >>> ioctl returns 0 >>> [root@btrfs progs-unstable]# btrfsctl -A /dev/sdc >>> ioctl returns 0 >>> >>> >>> /dev/sdb has a btrfs, while /dev/sdc is blank.

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 majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
