XFS Filing System

I have an external HD formatted to XFS.

When I connect the drive Tiger doesn't recognise this FS so I can't read the disk, which is a pity as there are files on it I want to transfer to my iMac.

Does anyone know of a way to do this?

Connect the drive to a computer that can read the filesystem and can also read/write either FAT32, NTFS, UFS, or Mac OS Extended. Attach a second drive so formatted and copy the files to that drive. OS X can read/write FAT32 and UFS formatted drives. It can also read-only NTFS formatted drives.

Alternatively if the two computers can be networked you may be able to transfer the files via Ethernet.

If there isn't a lot of data involved you could put the files into a ZIP archive and email them to yourself. You could put the data on an ISO 9660 formatted CD/DVD.

Thanks for the advice Kappy.

Ah but I don't appear to have access to a computer that will read XFS: I have two networked computers here; my iMac and a PC running Windows XP and to my knowledge neither will natively read XFS.

I have a NAS drive with a USB port to connect a second external drive (the drive in question) but unless I format the second drive under NAS management I can't use it via the NAS server. XFS is the only NAS format supported (no suprises there).

I'm probably being extra cautious here but I'm looking at a "what if the NAS unit fails" scenario, so don't want to be completely reliant on it.

I could connect the second drive directly to the iMac and do a another backup but why bother because the NAS does scheduled backups to the second drive.

I assume the files you want are on this NAS device? If so why not connect a FAT32 or Mac OS Extended formatted drive to one of the computers that has network access to the NAS device. Then copy the files you want from the NAS drive to the drive that you can read on the Mac.

I guess because everything is networked I don't really see what the problem would be in simply copying from the NAS device to any other drive connected to any computer on the network regardless of how any of the drives are formatted.

Maybe I'm misunderstanding your situation. I have five computers on my home network as well as a NAS device that is accessible wired and wireless. All the computers along with any external drives can be used interchangeably to transfer to or from the NAS which is Linux based.

I'm probably not explaining myself too well.

My external USB drive is a clone of the NAS device done under NAS. If the NAS device fails, I'm in a big jam because I can't directly connect the external USB drive to any computer as neither can read XFS.

As I said I'm looking at a "what if..." scenario here - the existing system works fine because I can access the external drive via NAS.

As a matter of interest, do you run your NAS device 24/7?

What if you connect the USB drive to one of the Mac computers and format it as Mac OS Extended. Then clone the NAS drive to the USB drive through the network. This way it makes no difference how either drive is formatted because the cloning is being done over the network.

Yes, my NAS is on 24/7. However, it automatically sleeps after 15 minutes of inactivity. That's configurable in the NAS firmware.

In retrospect I'm not as enamored with the NAS now that I have one. Aside from the fact that it's slow (even over gigabit Ethernet) it also has major limitations with respect to filenames. You cannot use any Unix/MSDOS illegal characters in filenames. So I have to screen and rename files and folders before backups. I've since taken it offline and returned to my old system of simply backing up to external Firewire drives and dedicated internal drives.

Kappy, I'm grateful for your replies.

Yes, I must admit that the shine has gone off NAS for me too. As you say, it's not particularly fast and as for these illegal characters...

I'm interested in your idea of running the external drive from the iMac and cloning via NAS. I must admit to not knowing anything about this and will have too look into it as it certainly sounds like the answer to my problem. Presumably this method means the iMac's CPU isn't used when backing up NAS to external?

Hi Kappy

I'm getting there - slowly. I've now managed to format the external drive to FAT32 and get the NAS drive to read it so can move forward safe in the knowledge that if the NAS unit fails, I can just plug the eternal directly in to one of my computers to access data.

I've now realised that I cannot set a share on any external drive connect via the USB port as this is used purely to backup the NAS unit. Buffalo's supplied documentation does not give a lot of information on this.
