Is it possible to sync a share across all the disks? I don't see the option to be honest but I thought to ask in case i am missing something obvious.
-
My share setting is that I have the same folder over all the disks at specific levels. The point is that I copied the same file to the same path on a different disk and i didn't realise but yet through the shared mnt point it didn't show any different. I was using twice the space but didn't realise. My fault for copying by mistake. If the same file can exist on multiple disks what happens if it is a writable file that changes over time?
-
I added a new disk and then started moving some files between disks in order to balance out some space but I noticed that I had some disks with the same folders and files. I could even rename the folder one each disk and then look through shared mnt point that I had two lots of the same folder and files. I can't work out how this happened but could be due to copying data between mount points incorrectly? I didn't realise that could happen. Has anyone ever mentioned this before?

I bought one of those plugin dust air blowers and clean the case out twice a year now and my temps are looking perfect since 6.12.6 and in winter I can even remove the front fans now if I wanted to, which looks a lot better.
Still planning on moving to a new case at some point.
-
Is there any way to make the files while they are still on the cache writeable? If I download something and then want to remove it, I can't delete it until it has been synced to the main array. Is there a way to change the permissions on the cache drive so that I can delete through SMB?

2023 update on my build
Unraid
Logic Case SC-43400-8HS
Gigabyte GA-Z87X-UD4H
Intel 4670k 3.8ghz
8GB corsair unbuffered
8 Port SilverStone ECS04
3x 12TB SEAGATE
5x 6TB SEAGATE
550W Seasonic Focus Gold PSU
2x 140mm fan1x 512gb cache drive
Pfsensein-Win IW-RF100
Supermicro A2SDi-4C-HLN4F
4gb 2133mhz Unbuffered
60gb SSD
TPLINK EAP660HD
8 port netgear switch
UPS
Cyberpower 780w
Interesting to see the entire setup including another windows media pc, vero 4k, my LG CX and the unraid nas only uses 110watts at idle.

I finally bought a 512gb SSD for a cache drive cost me £25 and I couldn't believe how much it allowed for my main array to not be spun up and reduced disk temperatures of the array overall.

I did it

You can understand my hesitancy though? the button is in the same list as the start stop array etc.
-
I can see it shows format will create a file system in all unmountable disks and then shows the new cache drive on the left side as the only disk. When I click are you sure box it warns me it is going to wipe the disk etc. I just want to be sure this is not going to touch the main array, I don't think it will but I don't think it is clear enough for me to just do it without posting this for confirmation. Its only going to format the cache right and is there any other way I can format the disk, like with the array unmounted and just that disk selected?
-
OK thanks, sorry for being blind and doing no research on this one.
Seems like I might have a justification to add a cache SSD now though.
-
Am I correct in saying that there are no system logs prior to a reboot?
Is there an app I can use to backup syslog across the network then? I had a weird power cut and not sure what my UPS did and wanted to investigate the cause but it seems the logs start at the current boot up time.
Alternatively if the system logs could be copied to persistent storage that could help to solve it as well, is that possible. I could keep a copy on the main array.
-
Adding one more array would be a great addition because would allow for different controller on the same Pc to manage the drives. After 1 or 2 arrays is not realy feasible. The cache is useflul but having a few more arrays would be even more useful. I like unraid in how the data sits on the disks compared to zfs.
-
At the moment my main array is done through the pcie HBA connector but it would be possible to add more sata disks or pcie disks using ssd now that they are coming down in price. Is adding a second array on the roadmap or will that never happen in unraid?
-
There was some bad firmware that caused slow disks years ago on HP controller. https://community.hpe.com/t5/ProLiant-Servers-ML-DL-SL/Smart-Array-P420i-extremely-slow-writes/td-p/6497596
Might be the cause, try in MC over ssh between disks, that should cut out network as the cause.
-
Does it always throw up a parity check when there is an unclean shut down? Is that just a precaution or is there something that happens on a clean shutdown that makes parity integrity better?
-
By mistake I turned off the mains power and my unraid lost power and rebooted afterwards and started up without issue. When I started the array it kicked off a parity check, I only just parity checked a few weeks ago as done some new drives and with the weather being hot at the moment, it is not ideal for me to run a parity check. I did cancel the parity check, am I taking a big risk there? There was no writing to data drives going on when the power cut and all the data is fine.
-
never mind, I see you use the scheduling to add the cron for you...

Looks like I found the problem with the delete access. The Ownership of the files is set to user "nobody" instead of the user "windows username" which is the user for the rest of the files. Interesting that these files were created by the filezilla docker with the folder mounted in to the docker image. Previously everything was downloaded through my windows PC to the NAS shares and that is why they end up with the owner "windows username" group "users" that allows me to delete those files. So a simple chown -R username:users might be sufficient here? I wonder if there is a way to force that user on to those docker downloaded files.
So again completely unrelated to the parity change, just doing too many changes at the same time I guess
Chown worked fine so now just need to post in to the filezilla docker thread and try get those files to default to the correct user. otherwise have to setup a cron job to chown it i guess.
-
What i do is I add a user to Unraid with the exact username and password that I use in windows and then I have no problem adding the mapped drives after that. Then apply read write for that username to all the shares. Seems to do the job for me without changing the guest access gpo.
Then if you want a private share, you can set private on the permissions and then set no access on guest access but read write on your user that you added.
-
NFS problems definitely caused by vero 4k and changing network config. So not related.
SMB delete problem i think is smb permissions as i can delete over nfs. it says tower/nobody lacks permission. i tried reexporting the smb. All shares are public so not sure the issue, Not urgent so i will wait for any advice before doing anything else.
sorry for triple post.
-
From what I can see, it is only affecting files and folders that were shared to a filezilla docker, I have removed the docker completely but they are still read only. I can remove other files and folders from other shares. Strange one.
-
Data drive replaced fine but still have the read only on windows over SMB, not deleted over nfs. Is there an issue?
Any reason for me not being able to delete folders/files over SMB after a parity drive change? Do I need to reboot?
NFS seems fine now but not tested deleting from NFS.
-
Does the array need to be stopped or not in an array operation in order to get a good backup? To what extent will I need to keep the backup up to date, will it only be array operations like replacing disks or do I need to do it after every parity check?

Cannot connect to unRaid shares from Windows 10

You have to add the windows user in to unraid. Then enable that on the share. Click on users then click on the windows user that you added then you see all the shares, set read write. then in windows map a drive to the \\ipaddress\share name using the windows user account.
