Red Hat Bugzilla – Bug 199866
Anaconda fails to enable swap on md device
Last modified: 2008-05-06 12:09:37 EDT
Description of problem: When trying to upgrade from FC4 to FC5 it stops early complaining that md1 is not a swap partition. In more detail: I am trying to upgrade remotely using kickstart. The boot line looks like this. ks=hd:sda1:/ks.cfg display=... ramdisk_size=8192 console=tty0 console=ttyS0,9600 The root partition, with /etc/fstab referred to in the message, is on another md device (ext3 on LVM volume on md2). So the raid assembly seems to work correctly. To further rule out this potential problem, I added mdadm assembly commands in ks.cfg to explicitly assemble all md devices. But I still get the same error message from anaconda. How reproducible: Every time

Can you get /tmp/anaconda.log and /tmp/syslog from the system?
It is a bit tricky. I'm doing the upgrade remotely. I have access to the serial console and I give anaconda an X display to use. But I can't do a switch to a different vt and use the shell that ususally runs there. As soon as I have the opportunity I'll go locally to the machine and do this, but I'm not sure how soon that will be. Unless there is some way to access the log with the setup I have?
If you do vnc (add 'vnc' to the boot command line) instead of a remote X display, then you'll get a "hit enter for a shell" prompt on your serial console.
I tried vnc first. "vnc" and "vncconnect=..." on boot line. But then I hit bug 179635 instead.
But thinking about it, I never tried without vncconnect. Maybe that doesn't trigger bug 179635. I'll try it, and see what info I can get.
Without "vncconnect" the vnc installation worked fine. :-) So I used the shell on the serial console you told me about. Here is some more details: md0 and md2, with /boot and / respectively, are assembled. But md1 has not been assembled for some reason. I can see in the syslog that it tries to assemble md1, and is looking at sda2. But it apparently never finds out that sdb2 is the other part. Why would that be? After that it gives up, and I suppose the remaining problems are consequences of this. In the shell I did a chroot to /mnt/sysimiga, and then "mdadm --assemble /dev/md1". That worked without problems. And after that, "swapon -a" worked too and started swap on /dev/md1. I should note that I am using the respin of 20060621 from Fedora Unity. To rule out the possibility it could be a problem introduced in the respin, I'm torrenting home the original distribution to right now. I'll come back with an update about this in a day or so.

raid autorun isn't ever looking at sdb2 -- does it have the raid flag set? (Run parted /dev/sdb, type print -- see if raid is in the flags list)
I didn't think about checking that, but yes, it seems to have the flag. (parted) print Disk geometry for /dev/sdb: 0.000-190782.210 megabytes Disk label type: msdos Minor Start End Type Filesystem Flags 1 0.031 400.056 primary ext3 boot, raid 2 400.056 4494.748 primary raid 3 4494.749 190782.210 primary raid
The behaviour is the same with the original FC5 DVD distribution. The problem is not introduced in the respin.
