Morning
We have some failing hardware in an oss (md raid5 over 6 x 750GB sata
disks) and I would like to migrate all the data off to a new oss.
This looks relatively straight forward enough, but can you do it semi-
live?
What I want to do is mount the lustre partition read only while it is
still being served up and rsync the data off to a new oss (which will
take ~24hrs). Then, bring the entire cluster down, do the last rsync
(which will hopefully be fast), turn the old oss off and bring the
new replacement oss into the cluster. In this way, downtime will be
minimised.
Will this work? Has anybody tired such a scheme?
Thanks.
