mounting external XFS HDD

[rativid]

I'm try to mount my external HDD with XFS but i got error:

mount_xfs /dev/sd0a /mnt/flashdrive/ 
mount_xfs: Device not configured

dmesg:

umass0 detached
umass0 at uhub0 port 3 configuration 1 interface 0 "JMicron USB to ATA/ATAPI Bridge" rev 2.00/1.00 addr 2
umass0: using SCSI over Bulk-Only
scsibus1 at umass0: 2 targets, initiator 0
sd0 at scsibus1 targ 1 lun 0: <SAMSUNG, J1TL415479, 0-12> SCSI2 0/direct fixed
sd0: 286168MB, 36481 cyl, 255 head, 63 sec, 512 bytes/sec, 586072368 sec total

Kernel have XFS option
What are I'm doing wrong
Thanks in advance

I see two problems, the second is just me over-analyzing.

1) mount_xfs(8) is not for SGI's XFS file system:

The xfs filesystem was written primarily to make a free, AFS-compatible filesystem (Arla). But since the xfs interface is simple and generic it could be used for other filesystems as well.

2) sd0a is likely the wrong partition.. but #1 makes this point irrelevant.

sudo mount -t msdos /dev/sd0i /mnt

that's it.

if you have more than one scuzzi and this doesn't work, try sd1i, sd2i, sd3i etc. depends on the number of scsi's.

Not necessarily. If nine other FFS partitions exist on the disk, then the first foreign filesystem will be lettered "j". The definitive answer is to check the output of disklabel(8) to find the exact partition letter.

There is no guesswork needed. Given the OP:

USB attached devices will be identified in the run-time messages sent to the console & appended to the end of the dmesg(8) buffer. In this example, a USB device was attached to /dev/sd0.

Some may wonder why "i" is typically seen as the partition of MS-DOS partitions. Disks can only identify sixteen partitions, & "i" is the mid-way between the end-points "a" & "p".

@tetrodozombie, that will only work if there is a recognized MBR partition with an MS-DOS (FAT) file system on it.

The device that mounted, per the post, was sd0. To see what MBR partitions are on the drive, ratavid can try:
# fdisk sd0
If one (or more) of those partitions is FATnn, then ratavid can use:
# disklabel sd0
to see if the MBR partition(s) have been assigned virtual BSD partition letters. These start with "i", if "i" is unused.

(EXT2/3, FATnn, CD9660, and UDF are the only supported foreign media-based filesystems supported by the project. NTFS is experimental, requires a custom kernel, and has other caveats.)

This is a horribly outdated post made a few years back, no doubt by a user who is long gone.

Why are you reviving it Bill? especially with information that is generally known and/or mentioned in the FAQ?

Heck, even my response to him is outdated, mount_xfs was renamed mount_nnpfs as few releases ago.
