 Subject: Re: Software RAID question

 I took a break from converting /dev/sd[ab]6 to a raid partition for a little
 while and noticed that selinux was complaining (the data has been moved from
 system to system before selinux was part of the distribution) so I disabled
 selinux.  Later I gave it one more shot at creating the raid volume and it
 worked.  I didn't link selinux to building of the raid partition until I read
 your response.
 
 My next question is... what do I do about selinux?  I've always disabled it
 because my system has always complained about something not being right with
 this file or that file.
Well, it you disable the selinux, change something (files, folders) and 
enable-it back without reseting context on files an folders, probably 
nothing will work anymore.

If selinux is enabled, and something does not work (not just a silly 
message from audit daemon - something REALLY does not work) just create a 
custom policy. man audit2allow

Software RAID question

2009-12-13 Thread Jeffrey Ross

I'm trying to mirror my two disks in my system (F12 x86_64)...

I have the following disk partitions
Filesystem   1K-blocks  Used Available Use% Mounted on
/dev/md127 7692840508960   6793104   7% /
tmpfs  1016196   260   1015936   1% /dev/shm
/dev/md1380760 44094316993  13% /boot
/dev/sda6  7684844   3956688   3337780  55% /usr
/dev/md5   7692776418204   6883800   6% /var
/dev/md7 934037448 388908936 497682148  44% /home

I am trying to get /dev/sda6 and /dev/sdb6 to become a RAID-1 volume...

I have created /dev/md6 as a degraded array and copied everything from 
/dev/sda6 to /dev/md6 in single user mode (actually booted from the 
recovery CD) and after mounting both partitions ran find . -depth | 
cpio --passthrough --reset-access-time --make-directories 
--preserve-modification-time /mnt2  (/dev/md6 was mounted on /mnt2).  
The copy took a few minutes and completed successfully.


I then modified my /etc/fstab to read (only showing physical disks) (I 
commented the old UUID and added the new UUID)


UUID=abcf3490-11d2-4641-bf47-c33d1614066d /   ext4defaults 1 1
UUID=e28d03fe-50ec-4313-a281-f1abecd4ed10 /boot   ext4defaults 1 2
# following is /dev/sda6

# following is /dev/md6
UUID=e0eb5abe-1765-48f7-923f-da8295b54313 /usr   ext4defaults 1 2
UUID=e35b19c3-b303-49fc-87d4-0712ac3de571 /varext4defaults 1 2
UUID=6f6600c4-5577-4617-b312-649fc2e2706a swapswapdefaults 0 0
UUID=93cc01f6-98e7-445b-bdc4-37356588e957 /home   ext4defaults 0 0

My mdadm.conf file reads -

MAILADDR root
ARRAY /dev/md1 level=raid1 num-devices=2 
UUID=1c0ba7ba:5b4e8354:14c0bbc3:de3ed72e

ARRAY /dev/md6 level=raid1 num-devices=2 
UUID=9b98d1c6:73b621e1:14c0bbc3:de3ed72e



The entries for the disks in /dev/disk/by-uuid -
lrwxrwxrwx 1 root root 10 2009-12-13 15:44 
3b891301-1b89-447b-81e3-4ddc5c835b3f - ../../sda6
lrwxrwxrwx 1 root root  9 2009-12-13 15:44 
e0eb5abe-1765-48f7-923f-da8295b54313 - ../../md6



I copied the initramfs-2.6.31.6-166.fc12.x86_64.img file to another 
directory and decompressed and extracted it and the only reference I 
found in there to the raid disks was in etc/mdadm.conf which was 
identical what is in /etc/mdadm.conf


I can mount /dev/md6 manually (as something other than /usr) with no issues


I think I'm missing something pretty simple, another set of eyes would 
be appreciated


TIA, Jeff

I assume that the new setup doesn't boot? (You didn't mention what's
wrong.)

What is the new partition type? (Should be Linux raid autodetect or
fb)

.. As for your fstab, why are you using the UUID? I usually remove the
UUID's and use the actual device name, IMHO its far easier to work
with...
