Description of problem:

Miss some hard disks during text mode ISO installation process

Version-Release number of selected component (if applicable):

Redhat7.4 Beta ISO

How reproducible:


Steps to Reproduce:
1. have 7 hard disks connected into Taishan 2280（here I just used 7 hard disks 
   to do test in Huawei Lab）
2. start ISO installation
3. can not find /dev/sdd in "Installation Destination page" in text mode 
   installation
4, alt + tab to enter the anaconda shell to check hard disks, we can find
   all 7 hard disks including /dev/sdd.

Actual results:

 can not find /dev/sdd in "Installation Destination page" in text mode 
 installation

Expected results:

 should see all hard disks in "Installation Destination page" in text mode

Hi Martin,

Any update about this problem?

Thanks
Zhou

Thanks for the logs!

Looking on storage.log the sdd device seems to be part of biso raid & seems to be the only such device present:

So my guess is sdd being bios raid but not being part of any array could be the reason it does not show up in the UI.

In any case, reassigning to the blivet (the storage library used by Anaconda) for further triage.

Exactly, it looks like there is some old metadata on the device. Is there a chance to try to reproduce the issue after running 'wipefs -a' on all the disks? Thanks!

Vojta, could you please keep an eye on this BZ? Thanks!

Zhou Wang,

I believe you were asked to do something in Comment #10

Have you done that?

Sorry for late. I run wipefs -a /dev/sdd (we miss /dev/sdd before). Then I tried to install ISO, /dev/sdd can be found now.

Okay so can we close this?

I don't know. If this is the expectation of blivet, we can close this bug.

However, once we meet a hard disk with old metadata, we should firstly manually
run "wipefs", then we can see the hard disk.

Yes, I guess we can close this now. If blivet sees a disk like that we have no way how to tell if it is just some "old" metadata or if it the disk is actually part of some unknown/unsupported firmware RAID (or something like that). So yes, this is an expected behavior.

OK
