unable to mount tape with mountlto #189

Closed DK10101 closed 5 years ago

DK10101 commented 5 years ago

Hello All

I'm quite new to LTO / LTFS and I'm reaching out as I feel you may be able to point me in the right direction.

$ mountlto Checking for ready tapes... Checking for tape barcode..... Checked 1 decks and none appear to have tapes ready to mount.

Any tips on getting this tape to mount successfully?

Background:

I have recently acquired an standalone mLogic LTO-6 Thunderbolt tape drive. I've had issues with the mLogic GUI- i have transferred 3 folders of data in 3 separate sessions, however I am unable to access this data. When I mount the tape through the GUI I can clearly see that 2.4TB are 'in use' as it is noted below the options menu, however when I go to retrieve this data it is nowhere to be seen. It seems that the tape is being partitioned and I'm unable to see / access these partitions. The tape is also not visible in my 'volumes' in finder, which is strange as I'd have thought it would appear there like any other drive. It mounts through the following:

/Users/editor/Library/Application\ Support/mTape\ LTFS\ Utility/.MountIndexData/147291539

I initially named the tape AAL210 and it would appear as such when I see the drive in Mac 'Computer', however now it appears as a 9 digit number instead of the tape ID I assigned it.

What I'm trying to do:

I'm currently trying to access the tape through terminal using LTOPERS in an attempt to access all of the data on the tape. I keep running into an error and the tape is unable to mount, perhaps you could point me in the right direction. Here is some additional information.

Thanks in advance, Dean

There's a line at https://github.com/amiaopensource/ltopers/blob/09062b5b9d0dcb1156222419764d070d928507b5/mountlto#L53, where the output of ltfs -f -o devname=0 is grepped for the barcode and with your output that value is . since that follows the barcode in

307 LTFS17227I Tape attribute: Barcode = AAL216 .

The process to get the barcode value from that output should be updated to find the barcode value rather than the last value in the line as it currently does.
