Hi
Sorry for the delay. It can be a bugger to get an environment on a
laptop that won't boot USB devices to a state where you can access the
PV and store something from it.
Well - could you post somewhere for download 1st. MB of your
PV device?
dd if=/dev/sdX of=/tmp/upload_me bs=1M count=1
You should be able to get that from:
http://www.interlinx.bc.ca/~brian/lvm-pv.img
Have you already tried to restore in some way ?
I have not tried anything yet for fear of making things worse ("angels
tread" and all that), so this is a blank slate from the point of it
first failing.
Hi
So it seems your machine has crashed (you probably know better) during
thin-pool resize operation.
Unfortunately fc23 has lvm2 version 2.02.132 - and version 2.02.133 has
improvement patch to make the resize more resistent (but still not as good as
I wish to be).
So what happened - lvm2 resized _tdata LV - tried to resumed it - and
it has failed along this path - however since the 'resize' is ATM a single
transaction - the lvm2 rollback reverted to previous size - yet thin-pool
already managed to remembered 'new' bigger size.
So please take a look at your logs (if you have some) if there
is something suspicious to be mentioned (thought if you machined
has freezed, hardly any log will be available).
To get access to your thin-pool - I'm attaching restored metadata content from
your disk header with 'bigger' _tdata volume.
To restore use:
'vgcfgrestore -f back --force brianr-laptop'
It would be really interesting to know the reason of failure - but I can
understand you could hardly obtain.
Regards
Zdenek
