Thank you for your previous response. My bad on not responding. I must have missed the notification and this fell off my radar. I am running reiserfsck right now to see if it finds anything. I am reviving this thread and will update once I get a response back from the command.

Closed this issue. Seems I posted about this already a year and a half ago and just notice the comments

I have a directory on a disk I am trying to get converted from reiserfs to xfs and just tring to make sure i moved everything off. but I have one directory I cannot access. If I try to cd access the directory via smb I get permission denied and if I try to ls to it or run du -h on the parent drive I get the "Exec format error". Anything I can do here or provide to you to help me figure this one out? Thanks! root@UNRAID:/mnt/disk1# du -h 0 ./tftp 0 ./.apps du: cannot read directory './Videos': Exec format error 0 ./Videos 0 ./Movies-PG13 0 ./TV Shows 0 ./appdata 0 ./Audiobooks 0 .

Getting the following on a directory. Cannot browse it via Windows explorer. I get the following: Permissions seem fine: root@UNRAID:/mnt/disk1# ls -al /bin/ls: Videos: Exec format error total 0 drwxrwxrwx+ 8 nobody users 176 Mar 14 07:07 ./ drwxr-xr-x 25 root root 500 Mar 11 07:04 ../ drwxrwxrwx 7 nobody users 256 Nov 3 09:42 .apps/ drwxrwxrwx 3 nobody users 160 May 26 2021 Videos/ drwxrwxrwx 9 nobody users 288 Mar 13 2021 appdata/ drwxrwxrwx 4 nobody users 352 Apr 12 2018 tftp/ From the console I cannot even cd into the folder root@UNRAID:/mnt/disk1# cd Videos -bash: cd: Videos: Exec format error root@UNRAID:/mnt/disk1# Thank you in advance for the help!

This keeps happening to me and I thought it was because I was installing new disks one which was a white label WD so I was trying to see if I needed the 3.3v mod for my back plane and was generally messing around with preclearing disks etc at the time that a parity check was happening. But I just hard booted the array because I lost access to the GUI yesterday and I removed the extra disk I was messing with before the hard boot. I stopped the parity check and the gui went non-responsive. SMB shares also are not responding. But I do have SSH access to the system. I initiated a powerdown -r. Based on my reading this actually performs a clean reboot of the system. Is this true? Could someone please check out my diag files to see if anything jumps out. Nothing jumps out to me. I see my version of unraid is a bit behind version wise. Should I upgrade it to the latest? Thanks! unraid-diagnostics-20220108-0716.zip

Thanks. It completed and now I can write to my shares. I appreciate it! Now to figure out how to get everything over to XFS. I do have alot of new drives to put in the system. Is it still recommended to preclear drives before putting them into the array? Is that a thing with XFS?

I just clicked the button that ran the reiserfsck without options. I dont know what options it used by default. But the check came back with some errors specifically about the rebuild-tree option. So I researched that option and put it in to run it as options and saw the other message. Thanks!

I have been having issues writing new files to my smb shares. All of my disk show green in unraid. So I have been assuming this was some permissions issue because I use the Active Directory integrated option and I had to prevously remove the unraid system from the domain and readd it. But now I really want to write new files to the system. In the logs I see entries like this. These are older entries but there are entries dated for today that have the exact same messages and disk/device: I went to run the fsck command with the --rebuild-tree option and the message dissuaded me from letting it continue so I cancelled the reiserfsck run. I have extra disks I can install into the system but wanted to check for guidance just to make sure I go about this the right way. BTW my diagnostics are attached. Any help would be greatly appreciated. Thanks! unraid-diagnostics-20220101-1259.zip

Yup I understand. I needed to get things back up and running. I could connect to unraid 6 web gui so I know that was working and I looked at tons of articles on the forum here about SMB but ultimately needed to go back to 5 to put the media back online. When I get some time I will try again. I tried connected to my local domain and not connected to the domain. In any case I know the ip address was fine. Will give it another go when I get a chance. FYI I did a straight flash wipe build. Added my drives into the array. Going to 6 appears to require a rebuild of the parity so there was no real reason for me to wait off and rebuild parity in version 5 before trying to upgrade. Now if there is some way to keep parity when upgrading to 6 I would really appreciate knowing how to do that. I figure maybe its possible to copy over a few files and move forward without having to rebuild parity. Any clue on that?

I did and I upgraded to 6.6.5 but then lost my ability to connect to SMB with my windows systems. So I switched back to my 5.0 install. This is very disappointing

I had to hard power off my array. It now needs a parity check. Should I do the parity check first before upgrading to 6? I am currently running on 5.0. Thanks, Scott

I guess we will mark this as solved. Thanks!

Thanks for the expanded information. Right now I have 13 data drives in my unraid. I have 3 more 8TB drives to add to replace 3 of the older 3 or 2TB drives I have in the system. So it seems like the best way to do it is to just replace 3 drives 1 at a time waiting for the rebuild/expansion. Once they are added move the files from the other smaller/older drives I want to remove from the configuration. Do the 'new config' utility and then reassign the data drives which I want to leave in the array. Making sure the not assign a data drive to the parity drive then let the parity rebuild once I start the array back up. Does that sound right? The 'new config' utility doesnt wipe out my plugins does it?

Well I have to move the data from the drive anyways and place it onto one of the larger drives I "drive swapped" into the array. So its not really about time. Although it saves the time of having to recalculate parity if there is a way once I have moved all the data off the old drive I will be removing from the array completely.

Yeah I just ended up doing a swap. Still I am going to need to know how to just remove a disk or two once I remove some of these older disks from the array. Is there a way to get them removed without having to recalculate parity?

I copied all the data off of a failing disk. How can I remove the disk from my array or replace it with a larger disk without having to recalculate parity? Anyway or should I just fail out the disk and then replace it and let the rebuild take care of it?

Yup... I got it back online. I just need to do a parity check. But for now I am good.

I have the SM SC846 and it looks like maybe one of my controller cards died during a power event. (power supply died) I am going to try to figure out which card died and once I do then put the drives back in on the existing good cards. Does it matter if the drives arent back on the same /dev/sd[bdefg] devices, as long as I assign the right drives based on serial number to the missing parity, disk1, disk2, disk3 etc disks? Please let me know. Thanks Scott

Thanks!

I dont have to do anything special?

I would like to know if I can run preclear on drive in a different system then installing drive into the array array. When I run preclear in my array on the new drive I saturate my io backplane and cause performance issues. So, can I run this in a different system and then install the drive then add it into the array without performing preclear?

Well my repair finished. I lost about 1.5 TB of data. Now have the arduous process to look at the files in the lost+found directory. Learned my lesson. Building parity now and will be looking at offsite backup for important files. Thanks!

I read it and now that I am running my commands on the correct disk this is what I am seeing: root@UNRAID:/# reiserfsck --check /dev/md8 reiserfsck 3.6.21 (2009 www.namesys.com) ************************************************************* ** If you are using the latest reiserfsprogs and it fails ** ** please email bug reports to [email protected], ** ** providing as much information as possible -- your ** ** hardware, kernel, patches, settings, all reiserfsck ** ** messages (including version), the reiserfsck logfile, ** ** check the syslog file for any related information. ** ** If you would like advice on using this program, support ** ** is available for $25 at www.namesys.com/support.html. ** ************************************************************* Will read-only check consistency of the filesystem on /dev/md8 Will put log info to 'stdout' Do you want to run this program?[N/Yes] (note need to type Yes if you do):Yes ########### reiserfsck --check started at Sat Jan 2 23:06:34 2016 ########### Replaying journal: No transactions found Zero bit found in on-disk bitmap after the last valid bit.

Hey RobJ, Unfortunately I just realized the additional bonehead move I made. So what happened is I had 9 disks in the array. Disk1 failed. I installed a new disk into the array and precleared it. I cleared the config and then added the drives back into the array. I was trying to install the new precleared disk as the parity drive. But I installed it as data drive and installed one of the existing data drives to the parity drive. I brought the array online with the data drive assigned as the parity drive which started the parity sync. I did cancel the parity sync but not right away. Is there anyway I may be able to salvage some of the data off that old good data drive which I inadvertently attached as the parity drive and started the parity sync on? At this point I have no idea what might have been on it. Hoping someone might be able to help. Thanks!
