Resolve `Failed SG_IO ioctl in ::getDeviceInfo Errno=5: Input/output error` errors" in Alma 9.4
requested to merge 743-investigate-failed-sg_io-ioctl-in-drivemhvtl-getdeviceinfo-errno-5-input-output-error-errors into main
Summary
This bug pops up for Fermilab on Alma 9.4. We also need a kernel patch as described in the originating ticket. But even then, after reboot if a tape is not explicitly rewound, the driver gives an input/output error.
Additional Required Actions
- Requires manual tests in pre-production: YES
Reboot a machine with Alma 9.4. Trigger a single read and that read should fail without this patch.
- Requires a documentation update: NO
