LTFSQuicktools failing to copy files to LTO-6 tapes
on Jun 13, 2017 at 10:56:26 am

Hi all,

Firstly many thanks for all of your help on these forums. I have never created an account before purely because I always find my question answered! This is a query that has been looked at before here but seemingly people have had new issues with it, and I'm wondering if it's a software update issue.

I use LTFSQuicktools software with an mLogic mTape Thunderbolt LTO-6 Drive. It's always formatted, mounted, written and unmounted just perfectly. However in the past couple of weeks I keep getting the following error when trying to write files to the drive even with a brand new formatted tape. (In this case, the total tape capacity is 2.41GB and available on the tape is 641.94GB, and the files I'm trying to write are 370GB in total):

"The item “[Project name here]” can’t be copied because it is too large for the volume's format".

Now I'm pretty sure this is an issue with trying to write files larger than 4GB to the tape. However, I believe I have written files larger than 4GB to the tape in the past?

Please find my log below, that doesn't seem to log any failure codes:

LTFS9015W Setting the locale to 'en_US.UTF-8'. If this is wrong, please set the LANG environment variable before starting ltfs.

Any help would be hugely appreciated. I have an archiving backlog seriously building up and don't think I've encountered this in the past. Happy to post any more info or data!

Many thanks and kind regards,

Francis

I have been backing up LTO6 tapes on LTO 6 back up system for 2 years. Never had this issue. All of a sudden I can't copy files as I get VOLUME IS TOO LARGE ERROR

I tried old tapes and same issues. Then I formatted them, same issue. I am 1 month behind backing up stuff

Any help would be appreciated

I am on Mac OSX 10.11.6

Hi Jawad,

Desperately researching this, I managed to find the problem and it's a very easy fix!.

On this thread (https://community.hpe.com/t5/Tape-Libraries-and-Drives/HPE-StoreOpen-on-Mac-no-longer-can-store-files-4GB/td-p/6959897) they mentioned exiting Adobe Creative Cloud, and now my 4+GB files are copying perfectly.

So it seems that by exiting Adobe Creative Cloud, you should no longer have any issues.

Many thanks and kind regards,

Francis
