How to move iPhoto library to NAS

Yes you have been lucky and, based on the experience of many users on here over the years, that luck can run out suddenly and catastrophically. Be sure you have a good back up.

I don't know if it's luck or not but a iSCSI attached LUN is not a network share.

It's like having an external drive connected on thunderbolt for example and formatted using HFS+ journaled.

It is a network share.

In computing, iSCSI (ⁱ/aɪˈskʌzi/eye-skuz-ee), is an acronym for Internet Small Computer System Interface, an Internet Protocol (IP)-based storage networking standard for linking data storage facilities.

If it's over IP it's network

In computer storage, a logical unit number, or LUN, is a number used to identify a logical unit, which is a device addressed by the SCSI protocol or Storage Area Network protocols which encapsulate SCSI, such as Fibre Channel or iSCSI.

There's that word Network in there again...

Sorry it's NOT a network share like those using SMB, AFP or NFS...

It's a real block device directly handled by the client OS (not the server) that can't be shared with anyone.

The IP part is only the transport layer as would be USB, SATA, Firewire, Thunderbolt, ...

Feel free to counter check if you want.

You know, whatever. It's on an unsupported drive. You've been warned.

I only want to share my knowledge with those searching for a solution to store their huge iPhoto Library.

The only real limitation is that the library MUST be on a HFS+ formatted drive directly managed by OSX. Nothing else.

Well Apple put it differently.

iPhoto needs to have the Library sitting on disk formatted Mac OS Extended (Journaled). Users with the Library sitting on disks otherwise formatted regularly report issues including, but not limited to, importing, exporting, saving edits and sharing the photos.

See this article

for more. Note also the comment:

“Additionally, storing the iPhoto library on a network rather than locally on your computer can also lead to poor performance or data loss.”

Yes, that's what i said 🙂

By the way : on network means on network shares 😉

(This is only because iPhoto relies on the hidden filesystem metadatas that are never transferred with protocols like SMB, AFP, NFS, … even if the server that shares the share is formatted in HFS+)

Edit : iSCSI is always to be considered as a locally attached device.

Dear

I am using a NAS Synology 412+ and a iPhoto library with 15k photo's. It's so slow I want to change the method.

How did you do the fast NAS setup? How can I see the NAS is formatted the right way?

If no change, I'll by a USB3 external hard disk....

Thanks for your help!

Buy the USB 3 disk, and format it Mac OS Extended (Journaled). That's what Apple supports.

An be prepared to lose all your files when the drive fails.

Thanks anyway.

Not at all - like any computer disk you will not lose anything when it fails because you know to always have a good up to date backup - not backing up is stupid

Huh? Isn't that why you have a back up - or 3... Or do you think NAS don't fail too?

Gofannon what Synology NAS do you have?

Thanks,

Kris

I have now a DS-415 Play and before that a DS-209+II

As mentioned here before, an iSCSI attached drive its to be considered the same way as an USB attached drive. No risk to have any data corruption problems.
