Hi guys,

I tried to upgrade F11 with soft raid F12. So far I used yum to upgrade Fedora 1 up to F11. My yum update went wrong and my server wes forcefully rebooted in the middle so none kernel from F11 works anymore.

After I booted F12 DVD - if I select "Install or Upgrade" and  "Replace existing Linux System" the probem is that my original raid raids are not mounted. I can see:

<6>md6: radi1: raid set md0 active with 2 out of 2 mirrors
<6>md0: detected capacity change from 0 to xxxx

<3>"Buffer I/O error on device md0, logical block 0"
...
<3>"Buffer I/O error on device md0, logical block 9"
<6>md0: detected capacity change from xxxx to 0
...
<6>md: md0 is stopped

This whole raid process repeats iteslf several times and it takes about 10-15 minutes.

However with "Replace existing Linux System" option, raid arrays are not mounted successfuly and I cannot install F12 over F11.

But when I select rescue option from F12 DVD, the same errors are displayed but my all old arrays are eventually mounted, so I can see all the files. Also once arrays are mounted they appear working and healthy.

Do you please have any hint how can I refresh or repair my md arrayrs so it does not take ages before these are mounted and at the first place they are mounted every time?
Is there any safe raid command I can do in rescue mode so this is achieved and I won't loss my data?
Do you think that my raid arrays created in times of Fefdora 1 can cause this problem?

This situation is very painful as I killed my day today trying to fix it without luck :(

Thank you very much gyus,

Jaiv

PS: During my initial tries I reinstalled swap (as it was encrypted on the old system and Anaconda always asked for pw which I do not have) and I did it with the command:
mkswap -f -L swap /dev/VolGrolup00/LogVol00
Do you think I could have damaged my raid arrays by using "-f" option?
