Hi All, I was upgrading my trusty old V5.05 Server to V6.7.2 but had some issues, I reverted back to V5.05 to fix some drive errors as recommended in an earlier post, I Fixed the main problem where a 4TB drive lost it's file system, however 2 disks were showing errors one was a 2TB Hitachi drive showing Pre-fail "relocated sector count", the other a 3TB WD Drive showing Old Age "Current Pending Sector". I have Precleared a healthy Samsung 2TB drive that I had sitting in a cupboard and replaced the Pre-fail Hitachi 2TB Drive with it, started the Array in Maintenance mode and started the Data Re-build, It all seemed to start off ok, I been to work all day come home to find the rebuild has slowed to a slow 2.68 MB/sec and it says its going to take approx 8 days to complete. The array is over 40TB in size with a mixture of mainly 3 and 4 TB drives in 15 drive bays. Any advise as what to do, something must be wrong. I'm terrified I'm going to lose data. Rebuiding: Total size:2TB Current position: 201.39GB (10%) Estimated speed: 2.68MB/sec Estimated finish: 11166minutes Is there and Diagnostics I can retrieve whilst it is running or can anyone offer any advice please? I appreciate that I should have upgraded much sooner, I have no excuse other than I have been pre-occupied and it was working fine as it was for years! I'm loving V6 and all it's benefits can't wait to get this system back to health so I can upgrade safely. Any help much appreciated. syslog-2019-10-02.txt

Thanks to everyone above who has helped me! I am now back up and running on v.5 and rebuild tree has completed. Thanks again to everyone who has helped me you have been awesome!

Doh! i'm just a bit tired now been a long day! Thank you.

Completed on Disk13 and says to --rebuild-tree. would I be better off replacing the drive and hoping that it rebuilds ok from Parity (or does it not work like that)? so am I best to "reiserfsck --rebuild-tree /dev/md13" OR to wait and replace the entire disk and let it rebuild? (Not forgetting I have 2 other drives that were showing errors when in v.6) that I was blissfully unaware of until attempting the OS upgrade lol I really appreciate the help guys!

thanks Frank I found that and running it now.

Hi thanks itimpi, I'm attempting that now. will report back how I get on.

I have booted back into V5.0.2 and Disk13 is still saying unformatted. I have ordered a replacement 4TB disk which should arrive tomorrow. I am not sure If I am better off just replacing the unformatted Disk with the new one or letting the system format it as it is.

was my browser! have attached syslog of V6 syslog.txt

I have a 4TB drive which was running ok on V5.02 which now says unformated. I have 2 drives with errors. Not sure what to do for the best, any help please? attached syslog

OH No! it was seeing one of my drives as an error (Disk 13), quickly popped my existing USB back (as parity drive would have needed rebuilding in v.6) and indeed one of my 4TB drives (Disk 13) now shows as unformatted. Any sugestions?

Thanks for the quick response, I have used the USB Creator tool and built and that is ready to use. Can I put this new USB drive into my existing server for testing purposes with my current drives, If it all seems ok revert back to my existing licensed USB then upgrade as new build? I am worried about the data staying intact not so bothered about the existing Apps etc. just don't want to lose any data, it currently has 15 drives mixture of 3 and 4tb.

Wish I had done it before to be honest, I upgraded from v.4 to v.5 but you know how it goes, busy life and it was working fine at the time so no need to fry fixing something that wasn't broken. My mistake! LOL Thanks for the response

Hello, My trusty old i3 array is still running v.5.02 it is quite slow now but with over 40tb of data I have been too cowardly to update it. My question is simply can I download the latest OS version onto a new USB drive as a trial instead of updating the current version? I'd like to test it without having to change any of the existing apps that are installed like Twonky. If my hardware is all good I then want to reinsert my old licensed USB and then update to the latest version. Any advise appreciated.

Hi, I was hoping someone would help me. My Unraid Server v:5.0.5 recently suffered a power cut which at first seemed to fry my Supermicro MV8 SATA Controller, but since removing and cleaning up the controller (re-attaching a heatsink which had fallen off) it now appears to be working. and I now have the array back up and running. This machine has been running fine with 14 data drives and one parity drive since 2012 so the components are getting old. I have purchased a new Controller, does anyone know If I can simply swap the controllers or is it much more complicated? I also would like to upgrade to V.6 when I know all is OK. Any advice welcome. regards David

Rebuilt Disk 10 and all seems fine, not sure why I have these troubles, I must be doing something wrong.

I now have a drive failure, Disk 10 2TB WEARS drive. I thought I had fixed my array after accidental removing Disk 3 What I did was coppied the files from Disk 3 to Disk 10 before removing the Drive replacing it (thinking I was being safe) it seemed OK. I bought it all back up and looked fine except I lost some permissions on some of the folders/files I had copied to Drive 10. I have run the New Permissions utility and now I have drive failure on Disk 10 Where this could be coincidental I am hoping it is salvageable and not really a disk failure. In the meantime today like an idiot I also replaced a smaller Drive 4 160GB with a new 2TB WDEARX which looks to be fine so I have plenty of room. Can anyone help me with what to do next please? not sure what to do now and don't want to make it worse. snippet from my log file is Jan 22 18:49:01 Tower kernel: sd 1:0:2:0: [sdi] Unhandled error code (Errors)Jan 22 18:49:01 Tower kernel: sd 1:0:2:0: [sdi] Result: hostbyte=0x04 driverbyte=0x00 (System)Jan 22 18:49:01 Tower kernel: sd 1:0:2:0: [sdi] CDB: cdb[0]=0x28: 28 00 e4 41 a9 c8 00 00 88 00 (Drive related)Jan 22 18:49:01 Tower kernel: end_request: I/O error, dev sdi, sector 3829508552 (Errors)Jan 22 18:49:01 Tower kernel: handle_stripe read error: 3829505640/6, count: 1 (Errors)Jan 22 18:49:01 Tower kernel: md: disk10 read error (Errors)Jan 22 18:49:01 Tower kernel: handle_stripe read error: 3829505648/6, count: 1 (Errors)Jan 22 18:49:01 Tower kernel: md: disk10 read error (Errors)Jan 22 18:49:01 Tower kernel: handle_stripe read error: 3829505656/6, count: 1 (Errors)Jan 22 18:49:01 Tower kernel: md: disk10 read error (Errors)Jan 22 18:49:01 Tower kernel: handle_stripe read error: 3829505664/6, count: 1 (Errors)Jan 22 18:49:01 Tower

not sure if it is just me being over tired but I haven't been able to add any attachment to my post

Hi, I hope someone can help me, I have searched the forum and can't find the answer i need. I am running unRAID Server Pro version: 5.0-beta14 with 16TB of storage over 12 drives maximum drive size 2TB I recently pulled a drive out by accident and followed instructions on this forum on bringing it back up, however my web console crashed and after many attempts I could not shut the server down without literally pulling the plug. now it is all back up but I have several folders and files in a couple of shares the I can no longer access from my network. I get an error message for example 'Windows cannot access \\tower\video\abc' When I look at permissions on the few effected folders it seems to be tower\administrators only. Do I run the Utils - New permissions utillity? I have a lot of important data and scared to click it before asking or is there a simple way of just restoring the permissions from the command line, bearing in mind I'm a linux newbie? Any help greatly appreciated
