It will do that. Spotlight stores the last-unmount-time so it knows if it needs to rescan. MacZFS stores this in a root xattr. We store it in a dataset value. So going between the versions will cause a rescan.
4> when I booted back into 10.6.7 it auto mounted my pool but it lost its zpool history? completely reset? I did not upgrade the pool or anything. Ideally I would have preferred to import it the first time as read only but it didnt give me the option... my recommendation is if a pool is exported it should not be auto imported the next time. it should only be auto imported if it was previously imported and mounted from the previous boot. ... but only if that is standard ZFS behavior since we want to stay compatible at the ZFS level.
I don't know about history, in theory neither version should remove history, but they did re-do how history works somewhere between pool v8 and v28.
I don't know how autoimport works in either versions, someone else will have to comment
5> I have 8gb of ram and no dedicated ssds since 10a286 didnt support it. Obviously I am not going to be able to run de-dupe.. should I make any other changes to settings to take advantage of features or just use ashift=12 since I am running 2TB drives and let ZFS set arc etc. When I do decided to switch over.. I will need to destroy my pool and rebuild it using ashift since I didn't before and then re-import from my backup. I have been using copy software to do my backups because it was keeping permissions and custom folder icons etc... would moving a snapshot be faster to copy my entire pool to the new set?
No dedup, ashift yes, and I would use compression=lz4. Snapshot with zfs send would be the best way to move the data. But rsync will suffice if you get the options right.
I have been running 10a286 on that machine since 10.6.. a long time... no data loss and TBs worth of data and media stored without issue.... is 1.3.1-rc2 stable enough to run on or are there crashes and data losses being reported?
No data loss, but its possible you will have deadlock or panic until they are remove. There is a plan for rc3 to come, but nothing too major in rc2.
if you can get in hooked back into the operating system and core storage a little tighter like it used to be.. I would be thrilled!!
The now famous issue116. It is coming.
