So when you say you "detach" a disk how are you doing that?

i just reconfigure a permissions and add a group

Code:
drwxr-xr-x 4 root root 4096 Aug 30 23:12 raid

Code:
drwxr-xr-x   3 root root  4096 Aug 30 12:39 mnt

Code:
drwxrwx--- 2 root admins  4096 Aug 31 08:54 test

smb.conf
Code:
[test]
path = /mnt/raid/test
valid users = @admins
read only = no
browsable = yes
guest ok = no
public= no

when deattach one disk, i cant see test folder in /mnt/raid/

After you created the RAID did you format it/create a new filesystem on it?

Did you see the resilvering process occur?

You are right to assume that you should be able to remove one of the drives and the volume still be available.

Does it also disappear if you detach the other disk?

This is what I did
Code:
sudo mkfs.ext4 -F /dev/md0

folder /mnt/raid/test disappear only. But this is only folder that I need.
/mnt/raid is steal present.

When you detach a disk, is the RAID still shown as mounted?

You might have /mnt/raid existing on your root filesystem which is covered when you mount /dev/md0 over the top. Then, if the RAID dismounts (although it should'nt) you will be left with /mnt/raid but the test folder will seem to be gone.

yeah raid is present, but inactive, no another disk.
How can i get my windows users allways have their files, and me also.
I cant get to lost my test folder.

I now deattach disk and no folder.
this is lsblk command
Code:
lsblk -o NAME,SIZE,FSTYPE,TYPE,MOUNTPOINT
NAME                    SIZE FSTYPE            TYPE MOUNTPOINT
sda                   232.9G                   disk
└─sda1                232.9G LVM2_member       part
  ├─johna--vg-root     227G ext4              lvm  /
  └─johna--vg-swap_1   5.9G swap              lvm  [SWAP]
sdb                     1.8T linux_raid_member disk

You posted this in "Unix for Beginners Question and Answers" but this isn't a beginners question so I'll move this thread to the Ubuntu forum proper in the hope that more Ubuntu experts will see it.
