You have been very patient with me and all my questions. I suppose it is getting your (my) head wrapped around it cause there is that back end thought that you don't want to lose data or mess up the array. I will do you recommendation and print things off, and make a game plan for when I am ready. I have (1X) 4TB pre-clearing now 38 hours in and another 4TB ordered in the mail, which will be pre-cleared. I don't know when I am going to exactly get to the FS change over as I have been working on a rebuild this past week with some questionable disks (sigh) I suppose after I am all changed over file systems (whenever that is) I will THEN add a second 6TB parity. I am assuming when running dual parity they both HAVE TO BE the same size (a match) ? Thank you for all the responses! I really appreciate the assistance, truely!

OK, right on! You can say I am kind of not overly familiar with some aspect of this, I wanted to ask to clarify. I really appreciate the response, and hope to see how it works going forward. Going to change it up now. Love the community. Thank you again (big time)! to reconfirm I posted my current changes below

should my plex container look like this? Temp directory = /transcode to /tmp

Ah I see what you're saying. I think your process is the 'reverse' of mine. 01) Add new pre-cleared disk (4TB formatted XFS) = 13 disks in array 02) remove (2x500 1x1.5tb) 03) run 'new config' 04) with 2x500 1x1TB out of the array... dock them via USB (attached to the server) and copy data back to the 4TB (XFS) 05) parity sync (for good measure) 06) done? I think... I can't mount disk 13 in the case properly until I physically remove the other disks (that will be a temp 'loose' hookup) On another note, I can have a mix of XFS and RFS file systems in the array, correct? Now to read up on how to format the pre-cleared disk XFS over RFS (which has been my default for years)

Hm interesting. Would that plugin read NTFS ? That would save a lot of time plugging the drive into a USB dock for sure. I think that is the best method for me (what i am thinking anyways) 01) copy data from array (2x) 500 + (1x) 1.5TB to external source 02) Remove disks 03) Run new config 04) parity sync/rebuild 05) add new disk (format XFS) 06) USB dock copy back to the XFS disk 07) Parity sync Then repeat as I have more space free in the case to add physical disks

OK I can try that method if the current disks in the array have enough room to move data to them The other option is to take the current data off, to an external source and then remove the disks, then add the new XFS disk, and copy content back to the XFS disk over the network I wonder how much XFS is going to make a difference. I hope a lot performance wise thanks -)

I did read it, and I keep looking it over :-) The troublesome part right now is everything I am trying to do. First off I am trying to shrink my physical disks in my array I am trying to replace disks (eventually) that are less than 3TB with 4TB At this point with the 12 physical disks in my case, the case is full (no more room to mount physical disks) So being that is the situation, where you state to start with largest DATA DISK in the set which is 4TB, and work down to migrate to XFS, I was looking at it starting with the smaller DATA DISK and moving that way. As you can see in my screenshot I have some 500GB and 1.5 TB drives. I could add (1x) 4TB disk and push all data from those 3 disks (or at LEAST 2 disks) to the (1X) 4TB drive. However after that is done, I want to remove them (2x 500 and 1x 1.5TB) completely from the array. What I am cautious about is UnRaid thinking I still have 12 disks when I really want to have (9X) in total at that point. I don't know what parity would do in that case, if it would say "hey missing disks/parity not valid" I think that's the point where you have to start a new config? I think I am being SUPER cautious, but I know once I learn it, I will understand it better. If I can AT LEAST get down to (9X) disks, I can then add another parity (for dual parity) and continue my migration to XFS. I really appreciate the help 01) Add empty drive (formatted XFS)02) move data from RFS drive to new XFS drive03) remove RFS drive Reformat RFS drive to XFS ^^^ these steps make sense and seem simple enough, but I have the added step of removing physical disks out of the array ^^^ I added "remove drive" (in steps above earlier) as I need to free up space in my case, a nice number to get to when finalized is (10X) disks. That make sense or am I over thinking things again (I do that sometimes) Thank you :-)

I am aware of the data rebuild as I am working on another concern with that The 6TB in my set is parity. How can I copy or clone parity to XFS ? Once I have a clone of parity, I then need another empty drive formatted XFS? So if I am understanding this correctly to convert my whole array to XFS 01) Add empty drive (formatted XFS) 02) move data from RFS drive to new XFS drive 03) remove RFS drive 04) replace removed RFS drive with new XFS drive (swap spots) 05) parity sync won't my parity think the RFS drive I removed is still an RFS drive when I try to sync? Being it is a XFS drive i am putting in that spot, doesn't parity go by last known FS table or something to that like ? On another note rather than migrating all drives to XFS (converting the array). Would it be a good idea, as I add drives or replace drives in the future going forward that I can have a mix of RFS and XFS drives in one array I.E. The next drive added or replaced to be formatted XFS, and added in replace of a drive, or wait... we can't-do that cause parity won't rebuild the data properly as it sees all current disks as RFS

So far so good

Hello, I would LOVE to change FS as I am using ReiserFS Still What would be my best plan of attack for this array? I feel overwhelmed thinking about it Thanks

That's exactly what I am experiencing When I do a file copy from Windows system to my array, it takes a while for it to fire up, and even then so, takes time during the copy to complete. I want to switch over, but that's a very very long tedious task it seems Reading about it, it seems clear and confusing at the same time That may be a task for another day, month, year. I just stuck with it when I started using Unraid back in version 3 or 4 (when I purchased it)

Thanks, I was reading that too :-) That's a big task! Is there a disadvantage to staying with RFS ?

OK that's good. Thanks for looking at everything! Currently Parity-Sync / Data-Rebuild 18.5 % So I hope everything goes well! I would love to move to the new file system! I wonder how much of a pain that is to do being there is data across all drives? I am sure there is a guide or tutorial ? Am I at risk of data loss converting ?

did you see anything else in my logs that are cause for concern by chance?

OK thanks for the help there. I am new to how some of these applications well. I know I am not utilizing some of my server functions efficiently. Right now I am in a rebuild/sync (due to another concern with disks) so I have to focus on getting my array 100% operational, then move to the next task of shrinking the array by removing smaller physical disks for larger ones, and adding dual parity. Every task takes some time :-) I am going to keep this thread open for the time being, as I am sure I will have some more questions. Still trying to figure out why those other plugins post "ERROR"

OK good to know. it's plugged into on-board (fingers crossed!)

updated sig as UnRaid version = unRAID Server Pro version: unRAIDServer-6.3.5-x86_64 Pro Here is the "original" disk3 that I pulled out initially WDC_WD40EFRX-68WT0N0_WD-WCC4EHXH65U4-20170927-1151.txt *********************** Replacement disk installed. Start will start Parity-Sync and/or Data-Rebuild. Yes I want to do this **************************** I am doing this now, it is going to take a good 20 hours I started this process, and DISK3 has a orange triangle next to it. Saying... device contents emulated Also, this disk is NO LONGER plugged into the SuperMicro SAS card, rather the Marvell on-board SATA port / chipset I have also posted NEW syslog.txt for any other info that may be needed syslog.txt

OK if SMART passes etc, and I rebuild it, and we still have a concern, i wonder what the next step is then Posted is the current disk status WDC_WD40EFRX-68WT0N0_WD-WCC4E0052905-20170927-1132.txt

OK I might have diagnostics sec what about the 3rd link I added?

The first disk replaced was JUST disabled. There was NO S.M.A.R.T issues with the first disk. I am currently pre-clearing a BRAND NEW WD RED, just broke it open and pre-clearing on another workstation/PC What would you recommend going forward. I have no problem purchasing a better, or recommended SAS card. I bought this back in the version 4 or 5 era. I would love a link so I can look it up. I still have a spare on-board SATA port I can use. Should I try the disk (replacement disk) on that SATA port? I also have a spare SATA cable on my breakout cables (on the other SAS port) Should I attempt that. Should I be buying a new card ?
