Hi folks,

I am trying to jcache some files:

[hsingh@ifarm2402 BCAL_LED]$ jcache get /mss/halld/RunPeriod-2026-06/calib/ver00/BCAL-LED/Run150191/hd_rawdata_150191_001.BCAL-LED.evio

but I am getting the following error:

get request: -1
status: failed
/cache/mss/cache/halld/cache/RunPeriod-2026-06/cache/calib/cache/ver00/cache/BCAL-LED/cache/Run150191/cache/hd_rawdata_150191_001.BCAL-LED.evio -> failed (not in tape library)

But I checked that files indeed are in the tape. Do you have any idea on what might be causing this issue and how to resolve this?

Thank you!
Best,
Harsimran

this is interesting:
jcache list /cache/halld/RunPeriod-2026-06/calib/ver00/BCAL-LED/Run150191/hd_rawdata_150191_001.BCAL-LED.evio
0 pin        taped    hd_rawdata_150191_001.BCAL-LED.evio

so it should be on tape? this is a very new file isn't it?

Hi Harsimran,

I'm seeing the same error. However, the path in the error message looks odd:

`/cache/mss/cache/halld/cache/RunPeriod-2026-06/cache/calib/cache/ver00/cache/BCAL-LED/cache/Run150191/cache/hd_rawdata_150191_001.BCAL-LED.evio
`

This path definitely doesn't exist. It appears that jcache inserted
additional `cache` strings after every 2nd segment in the original path.
Your best option is probably to open a ticket.


Just my two cents.
-Boris

I’m also seeing this error for recent files that should be on tape. I agree that this should be elevated to a ServiceNow ticket. Did you already do that Harsimran, and if so can you share the link to the ticket?

Hi folks,

Thank you for your attention to the matter. As Boris suggested, I emailed the helpdesk yesterday and here is the corresponding incident link.

Best,
Harsimran
