[btrfs or xfs for new server?]

No. Parity doesn't contain any data, it contains the entire disk, file system and all. If you format a disk, parity will be updated to reflect the change in format and the disk will be empty.

 

You must copy the data elsewhere or restore from backups, you can't convert in place.

 

There is an entire pinned thread and wiki article about file system conversions, it's mostly referencing ReiserFS, but the principles apply to any file system change.

https://wiki.unraid.net/index.php/File_System_Conversion

 

Thanks. I'm trying the procedure stated in that wiki - move the data out of the driver first and then convert it.

[btrfs or xfs for new server?]

How to convert BTRFS to XFS without lose data? I have one parity drive, but no extra spare disk. 

Is it possible to unassign the disk and re-format it to XFS, later recovery data via parity synchronizing?

Well neither command was able to mount it, so I am using the xfs_repair -vL command.

 

Have my fingers crossed, thanks.

 

EDIT:

Wow, by that other post, I thought it was going to take hours.

 

It finished and it is now mounted!

 

Thanks,  now I have to figure out why my Docker isn't working.

 

EDIT AGAIN:

 

Well that fixed docker also!

 

Twice power off inexpertly make one disk unmountable. First time clicked format - lost whole disk data. Second time xfs_repair -vL saved me! Thanks

[700 permission does not block other users reading the file]

Realistically, though for FTP access you're probably best off using something like ProFTPd

Thanks for your reply. As suggested I switch the default FTP daemon to ProFTPd. The permission of shared folder always  puzzle me. It changed itself and I have no clue.

[700 permission does not block other users reading the file]

Hi, I set a shared folder permission to 700 by chmod and the owner to root:root. 

But other users still can read the folder via ssh/ftp.

It seems the permission only work with samba share?

[Move share to cache drive only]

I used "prefer" for my "transmission" download shared folder, because I want to the active files (downloading/uploading) files stay in cache. But the result is some files never used were moved from array to cache, then stay there and no longer are moving out. Based on what rules the mover move files from array to cache with setting "prefer"?

Shoud I use "Yes" for my case - to store "hot" file in cache?

Hi jonathanm, I upload the diagnostic zip in my first post. I checked in shell with command: fdisk -l 

The new disk "/dev/sdc" was not there! It appear again only after I reboot.

Confirmed it's problem of hardware. After replacing SATA cable, the problem was gone. Please close the thread.

[[SOLVED] Cannot assign new disk for disk replacing]

Hello guys, one of my data drive was out of work. I follow https://wiki.unraid.net/Replacing_a_Data_Drive to replace it.

After I chose the new drive from the list, it disappear from the list and cannot be selected again.

The new drive is listed in the unassigned list. I try to format it but failed!

Have no idea how to do. Please help. THX
