So, as far as i understood - one disk removed array works, other disk array does not work ?
Did you use fdisk or (g)parted on those disks at all to put raid type ?
As for samba and your actual requirement, that is layers above. One at the time
First you need your md device to be redundant and working after reboot.
What is the HW on that server, since you can unplug disks live ?
I would advise against that practice to test redundancy, if not specifically supported.
You see disk fail in various ways, but rarely unplugging the cable or hitting it with an axe.
Testing will prove difficult
But from my experience @ home, i had an RAID1 array, one disk died of natural causes (old age) and the mdadm system did the job.
This was some time ago tho..
Can you show output of :
Code:
fdisk -l /dev/sdb
fdisk -l /dev/sdc
Have you considered using ZFS on ubuntu ?
It should really ease up the process of creating a mirror and managing it in a long run.
Yeah,u arr right. When i pull out on of the disks i cant access folder test where i mounted md0.
My only concerne is to secure those data. Ok samba is on the layers above and its not very important to users to access it,but files must be replicated each other when i put some unix based live system to backup or save files if one disk fail.
I didnt try anything,only madm

My only concern if i left it like this, does the data be readble from a some linux usb live system or not. Nothing else

Hi everyone! I'm trying to run a script when a folder is shared and when it stop being shared.
Is there something like .start_share or .stop_share scripts in Samba where I could run some commands?:confused:
edit: maybe with a wrapper in smbmount but I share folders via nautilus. Any ideas? (0 Replies)

mkfs.btrfs
MKFS.BTRFS(8) System Manager's Manual MKFS.BTRFS(8)NAME
mkfs.btrfs - create an btrfs filesystem
SYNOPSIS
mkfs.btrfs [ -A alloc-start ] [ -b byte-count ] [ -d data-profile ] [ -l leafsize ] [ -L label ] [ -m metadata profile ] [ -n nodesize
] [ -s sectorsize ] [ -h ] [ -V ] device [ device ... ]
DESCRIPTION
mkfs.btrfs is used to create an btrfs filesystem (usually in a disk partition, or an array of disk partitions). device is the special file
corresponding to the device (e.g /dev/sdXX ). If multiple devices are specified, btrfs is created spanning across the specified
devices.
OPTIONS -A, --alloc-start offset
Specify the offset from the start of the device to start the btrfs filesystem. The default value is zero, or the start of the
device.
-b, --byte-count size
Specify the size of the resultant filesystem. If this option is not used, mkfs.btrfs uses all the available storage for the filesys-
tem.
-d, --data type
Specify how the data must be spanned across the devices specified. Valid values are raid0, raid1, raid10 or single.
-l, --leafsize size
Specify the leaf size, the least data item in which btrfs stores data. The default value is the page size.
-L, --label name
Specify a label for the filesystem.
-m, --metadata profile
Specify how metadata must be spanned across the devices specified. Valid values are raid0, raid1, raid10 or single.
-n, --nodesize size
Specify the nodesize. By default the value is set to the pagesize.
-s, --sectorsize size
Specify the sectorsize, the minimum block allocation.
-V, --version
Print the mkfs.btrfs version and exit.
AVAILABILITY
mkfs.btrfs is part of btrfs-progs. Btrfs is currently under heavy development, and not suitable for any uses other than benchmarking and
review. Please refer to the btrfs wiki http://btrfs.wiki.kernel.org for further details.
