To all
One other issue that is probably worth including in this thread, is that of the different partitions in sme7 compared to sme6.
An upgrade install from CD on a existing sme6 will not change the partitions to the new sme7 format (sme6 has 3 partitions, sme7 has 2 partitions). There are other forum posts & bug tracker entries that refer to this eg
http://bugs.contribs.org/show_bug.cgi?id=572The effect of this is that an upgraded sme6 retains the old partitions and the "very nice" feature in the admin console panel to add a drive to a broken software RAID1 array WILL NOT work.
I believe the developers plan to fix this in a later release of sme7 (7.1 ?) so that the partitions are automatically converted during an upgrade, but no guarantees here.
The workaround (particularly if you want to avail of this new feature to easily rebuild a software RAID1 array in sme7), is to do a fresh install of sme7 either with one or two disks, as software RAID1 will be configured by default (degraded mode for one disk installs).
Then you can restore from your sme6 backup using one of the methods described, or just even manually reconfigure the new server from scratch.
