[Lustre-discuss] 1.8.1.1 -> 1.8.3 upgrade questions

[Gustavsson, Mathias]

Hi,

We tried to do a 1.8.1.1 to 1.8.3 version upgrade this weekend, but we got i/o error on all of our old file systems (created ~4 years ago), we have a more recently created filesystem (only a couple of moths old) and that was fine.
This was in the log of the active mds, i couldn't find anything related in the log of the client at the time.
