Re: [MooseFS-Users] MooseFS 3.0.77 - Stable Release

[Piotr R. K. <pio...@mo...>]

Dear MooseFS Users,

after some notifications from Users about incompatibility of 3.0.x Mounts with 2.0.x Master Servers, we decided to rollback default "stable" symlink in our repository structure to 2.0.89.

It doesn't mean, that MooseFS 3.0.77 is not stable!

We did it only to prevent compatibility issues of 3.0.x Mounts with 2.0.x Masters in Users' MooseFS instances.

We still recommend and encourage you to upgrade to 3.0.77.
It can be done by typing explicite "3.0.75" instead of "stable" in repo URL (as I mentioned in my previous mail in reply to Steven's mail - attaching in quote).

Tomorrow we are going to propose a better repository URLs structure.
Please watch the mailing list and our website <https://moosefs.com/download.html> tomorrow.

Best regards,
Peter

I was reminded of this today when I had to take down one of my MooseFS master servers to replace its UPS.  Since I was rebooting the master server, I decided to perform a full package upgrade on it (Ubuntu: apt-get dist-upgrade).  That, of course, upgraded all MooseFS components to 3.0.77 from 2.0.89.  But I have numerous MooseFS master servers still running 2.0.89 and the new mfsmount won't mount these older (2.0.x) MooseFS file systems.  I will probably mark as held the moosefs-client package on all my workstations until I have upgraded all MooseFS master servers to 3.0.x.  I hope this helps prevent an unexpected surprise to some other user!
