Is xfs_repair an option?
unlikely in case the underlying device has all sort of damages - think
of the RAID like a single disk and how the filesystem reacts if you
shoot holes in it
And, if it is, do I run it on md125 or the
individual sd devices?
when you think two seconds it's obvious - is the filesystem on top of
single disks or on top of the whole RAID - the filesystem don't even
know about individual devices
Unfortunately, restore from back up isn't an option - after all to where do
you back up 200TB of data?
on a second machine in a different building - the inital sync is done
local and then no matter how large the data rsync is enough - the daily
delta don't vary just because the whole dataset is huge
and don't get me wrong but who starts a reshape on a 200 TB storage when
he knows that there is no backup?
This storage was originally set up with the
understanding that it wasn't backed up and so no valuable data was supposed
to have been stored on it.
well, then i won't store it at all
Unfortunately, people being what they are,
valuable data has been stored there and I'm the mug now trying to get it
back - it's a system that I've inherited.
