Problem mounting HP LTO5 with HP LTFS 2.1.0

[Patrick Dung]

Hi quadstor,

I am emulating HP LTO5 drive using quadstor 2.2.8.
I can format the tape as ltfs but I am unable to mount it.

I have no problem using:
IBM LTO5 emulation with IBM lin_tape, IBM ltfs 1.3.
Quadstor 2.2.7.


I get the HP 2.1.0 LTFS from here:

Works  fine here both with the current code and 2.2.8 package with both HP LTO 5 and LTO 6. Further below are messages from our test which is similar to yours except that there are no errors.

Have you by any chance specified a maximum vcartridge size in quadstor.conf ? That is currently not supported with LTFS. But with that formatting should have failed.

We remember a similar issue when LTFS support was being developed. Is this problem consistent ? That is can you try deleting the vcartridge and try again. Also try with LTO 6.

Kindly also send the /var/log/messages file (off list). Maybe any errors are logged there.

Is the virtual tape drive on the same machine as /dev/st4 or connected via iSCSI/FC ?

1. I use the default vcartidge size.
2. I have tried to do a fresh install of quadstor-vtl 2.2.8  on rhel 6.3 x64.
I selected HP LTO5 as the vtape. But still have the same issue.
By the way, I am using the default Linux tape device driver. I have not installed the HP's Linux tape device driver.
I do all the test on the same server without iscsi.

I will send the log off list.

[QUADStor VTL Support]

Still no luck in reproducing this. Works every time. Looking back at
your original post, we dont seem to get the following messages.

LTFS11175E Cannot read ANSI label: expected 80 bytes, but received 4096
LTFS11009E Cannot read volume: failed to read partition labels.

It seems that in your first test the tape already had a partition 1 or
atleast mkltfs thinks so.
Could you try out the following in your setup.
1. Create a new blank vcartridge, and load that into the drive
2. mkltfs -o trace
3. ltfs -o trace

Now then delete the vcartridge.

mt -f <device path> compression 0
Repeat 1 - 3 and send us the logs for all the operations. That should
help us debug this better

[Patrick Dung]

Hi quadstor,

It seems turning off the compression looks good.

Please see the attached file.

Thanks,
Patrick

[QUADStor VTL Support]

This should be fixed in 2.2.9. Although we were unable to reproduce
this, based on your logs, we believe that the fix has gone into this
release. Please try with the new release.

Yes, I don't have problem with the new release, thanks!
