I activated your attached metadata in my testbed and get: # dmraid -r /dev/dm-16: isw, "isw_djddabgcfi", GROUP, ok, 976773166 sectors, data@ 0 /dev/dm-12: isw, "isw_djddabgcfi", GROUP, ok, 976773166 sectors, data@ 0 # dmraid -s *** Group superset isw_djddabgcfi --> Subset name : isw_djddabgcfi_Volume0 size : 1953536000 stride : 256 type : stripe status : ok subsets: 0 devs : 2 spares : 0 # dmraid -tay isw_djddabgcfi_Volume0: 0 1953536000 striped 2 256 /dev/dm-12 0 /dev/dm-16 0 Activation works fine and size of striped mapping makes sense. No reproducer here. Is temporary remote access to your machine possible to allow for analysis ? Heinz fpee, Fedora 12 uses mdraid for activation of ISW RAID sets, so most likely your set is already activated as /dev/md-127, which in turn is causing the failure of dmraid to activate it as it is already active. Can you paste the output of "cat /proc/mdstat" here please ?

I am seeing this issue. The filesystem on the RAID mirror is not getting mounted at boot time.

If you specify the correct (new) path to the device in /etc/fstab, any filesystem on there should get mounted without problems.

So if md is running the RAID, why is it being deactivated just prior to dracut switching root? # dmesg | grep md md: bind<sdc> md: bind<sdb> md: bind<sdc> md: bind<sdb> md: raid1 personality registered for level 1 raid1: raid set md126 active with 2 out of 2 mirrors md126: detected capacity change from 0 to 1500299594752 md: md126 switched to read-write mode. dracut: mdadm: Started /dev/md/Mirror_0 with 2 devices md126: p1 md: md126 stopped. md: unbind<sdb> md: export_rdev(sdb) md: unbind<sdc> md: export_rdev(sdc) md: md126 stopped. md: md126 stopped. This leaves me with a deactivated md RAID that will not mount: [root@mame ~]# cat /proc/mdstat Personalities : [raid1] md127 : inactive sdb[1](S) sdc[0](S) 4256 blocks super external:imsm unused devices: <none> I can stop the md RAID: mdadm -Ss mdadm: stopped /dev/md127 [root@mame ~]# cat /proc/mdstat Personalities : [raid1] unused devices: <none> And then use dmraid to configure and mount the devices: [root@mame ~]# dmraid -ay RAID set "isw_egcfjehcj_Mirror" was activated device "isw_egcfjehcj_Mirror" is now registered with dmeventd for monitoring RAID set "isw_egcfjehcj_Mirrorp1" was activated Then I have a usable filesystem. Ah, I understand your problem now :) Your Intel BIOS RAID sets are not listed in /etc/mdadm.conf, so they don't get re-activated by rc.sysinit, this is bug 537329, which is being fixed for Fedora-13. And the still active mdraid container keeps the devices busy causing dmraid to fail. Given that you seem to want to use dmraid anyways, you can work around this issue by specifying "noiswmd" on the grub / kernel cmdline, which will make dracut not use mdraid for the RAID set, and will make rc.sysinit properly activate it with dmraid. Add this to grub.conf to make it permanent. Regards, Hans *** This bug has been marked as a duplicate of bug 537329 *** |
