No IO devices added into mdt file

[davidzengxhsh]

I build and installed the htx. But when I start htx by htxscreen, the hard disk is not added in the mdt.all or mdt.io.

There is no partition or OS installed on sdb and sdc. Any other restrictions for hard drive scanning?

Disks should be raw disk for HTX to pick it up for testing. Even if any filesystem ever existed on it, it will not be picked.

Could you share "parted -mls" output here.

At beginning, both sdb and sdc weren't added into mdt.io. I manually modified mdt.io to include sdb and ran test. After that, htxscreen can add sdb into mdt file. But sdc is still can't.

Can you provide /tmp/part.pl.log file to look into.

[davidzengxhsh]

part.pl.log

device=/dev/sdc of type="ddf_raid_member" Detected !!

I think this is the problem! But I have written this disk using fio.

[mehuljpatel]

sdc being a RAID member would not be touched by HTX. I think, fio is a file system based test program and hence it would create a file system on the device. If you are very sure about testing specific device, you can manually add entry into mdt file and run HTX. Once you run HTX storage exerciser, it will overwrite LBA 0 and later, HTX setup would pick it up for testing automatically.
