Subject: mdadm what does it mean
Date: Thu, 20 Mar 2008 00:01:00 +0100 [thread overview]
Message-ID: <47E19B2C.2040901@grafikern.no> (raw)
Hi
I am using mdadm to manage my RAID arrays, but cant seem to find an easy
to understand or concise explanation of what the different parameters
mean when I write:
cat /proc/mdstat in the terminal.
The ones I can't even guess are:
super
bitmap
pages
chunk
Could someone please point me to such a place that will tell me this, or
if you are blessed with fortuitous amounts of time explain it to me in
an email.
My output when I write cat /proc/mdstat today is:
--------
Personalities : [raid1]
md0 : active raid1 sda1[0] sdc1[1]
488383864 blocks super 1.0 [2/2] [UU]
bitmap: 2/466 pages [8KB], 512KB chunk
md3 : active raid1 hdb4[0] sdb4[1]
183711232 blocks [2/2] [UU]
md1 : active raid1 hdb2[0] sdb2[1]
104320 blocks [2/2] [UU]
md2 : active raid1 sdb3[0] hdb3[1]
10490372 blocks super 1.0 [2/2] [UU]
bitmap: 0/161 pages [0KB], 32KB chunk
unused devices: <none>
--------
Any help or pointers appreciated. I tried reading through the man pages
but I am not any wiser. Or it could be that I just missed the relevant
sections.
