Re: LVM2 on raid6 partition recovery

Here, I point linux-raid users:
http://marc.info/?l=linux-raid&m=133121914429398&w=2
to this saga here that I wrote recovering my data on this forum.
Because, I believe there are questions as to how to prevent a loss like this one that nearly hit me hard!
I am dead tired.
So tired there is "a ...

Re: LVM2 on raid6 partition recovery

I didn't wait for so long...
But I will inform with a link to this thread other users at the linux-raid mailing list that I mention in previous post, because I believe it can be of use to other mdadm users.
Here's how the story is hopefully nearing a fine ending.
In case there is no power outage (I ...

Re: LVM2 on raid6 partition recovery

Official archive with Neil Brown's suggestion in similar situation is this.
http://www.spinics.net/lists/raid/msg34840.html
And yes, I'll look deeper yet, and then ask what I will be intent on issueing
at the command line on the linux-raid mailing list, to which I just subscribed:

Not yet gone anywhere.
Found and reading this:

It's "all spares" to be found there, and it's the author of mdadm's wrote there.
Be back.

Re: LVM2 on raid6 partition recovery

Here's something strange. Follow what /dev/mdstat says
on --assemble (-A) attempts of /dev/md127.
at8-g200@sysresccd % mdadm -S /dev/md127
mdadm: stopped /dev/md127

Re: LVM2 on raid6 partition recovery

Here's some more tries.

"Recovering a Lost LVM Volume Disk":

I'll be reading again and more on the issue. Now.
