Upgrade procedure to Gluster 5, from Gluster 4.1.x, 4.0.x, 3.12.x and 3.10.x
NOTE: Upgrade procedure remains the same as with 4.1 release
Refer, to the Upgrading to 4.1 guide and follow documented instructions, replacing 5 when you encounter 4.1 in the guide as the version reference.
Major issues
- The following options are removed from the code base and require to be unset before an upgrade from releases older than release 4.1.0,
- features.lock-heal
- features.grace-timeout
To check if these options are set use,
# gluster volume info
and ensure that the above options are not part of the Options Reconfigured:
section in the output of all volumes in the cluster.
If these are set, then unset them using the following commands,
# gluster volume reset <volname> <option>
NOTE: Failure to do the above may result in failure during online upgrades, and the reset of these options to their defaults needs to be done prior to upgrading the cluster.
