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.
Hi,
I am facing problem while accessing samba share on Linux 5.1 from windows, though I have done the same configuration on Linux 4 (Update 2), on Red Hat 4.0 it is working but while on Linux 5.1 these configuration are not working, I have disabled the firewall also.

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)
Hi I have an issue with a client. He was able to use his mounted Samba share for a long time. However, a couple of days ago, he wasn't able to access all of his files all of a sudden. He still see's the share and majority of the files, but not some that he needs.

fdisk
CFDISK(8) GNU fdisk Manual CFDISK(8)NAME
GNU fdisk, lfdisk, gfdisk - manipulate partition tables on a hard drive
SYNOPSIS
fdisk [options] [device]
DESCRIPTION
fdisk is a disk partition manipulation program, which allows you to create, destroy, resize, move and copy partitions on a hard drive using
a menu-driven interface. It is useful for organising the disk space on a new drive, reorganising an old drive, creating space for new oper-
ating systems, and copying data to new hard disks. For a list of the supported partition types, see the --list-partition-types option
below.
It comes in two variants, gfdisk and lfdisk. Lfdisk aims to resemble Linux fdisk 2.12, while gfdisk supports more advanced disk operations,
like resizing the filesystem, moving and copying partitions. When starting fdisk, the default is to run gfdisk.
OPTIONS -h, --help
displays a help message.
-v, --version
displays the program's version.
-L, --linux-fdisk
turns on Linux fdisk compatibility mode. This is the same as running lfdisk.
-G, --gnu-fdisk
turns off Linux fdisk compatibility mode.
-i, --interactive
where necessary, prompts for user intervention.
-p, --script
never prompts for user intervention.
-l, --list
lists the partition table on the specified device and exits. If there is no device specified, lists the partition tables on all
detected devices.
-r, --raw-list
displays a hex dump of the partition table of the disk, similar to the way Linux fdisk displays the raw data in the partition table.
-u, --sector-units
use sectors, instead of cylinders for a default unit.
-s, --size=DEVICE
prints the size of the partition on DEVICE is printed on the standard output.
-t, --list-partition-types
displays a list of supported partition types and features.
The following options are available only to lfdisk.
-b, --sector-size=SIZE
Specify the sector size of the disk. Valid values are 512, 1024 and 2048. Should be used only on older kernels, which don't guess
the correct sector size.
-C, --cylinders=CYLINDERS
Specify the number of cylinders of the disk. Currently does nothing, it is left for Linux fdisk compatibility.
-H, --heads=HEADS
Specify the number of heads of the disk. Reasonable values are 255 or 16.
-S, --sectors=SECTORS
Specify the number of sectors per track. A reasonable value is 63.
BUGS
Before editing a BSD disklabel, the partition with the disklabel should already exist on the disk and be detected by the OS. If you have
created a BSD-type partition, you need to write the changes to the disk. If fdisk fails to notify the OS about the changes in partition ta-
ble, you need to restart your computer. As fdisk tries to guess the device holding the BSD disklabel, it might fail to edit it at all, even
if the OS has detected it. In this case you are adviced to simply open the device with fdisk directly. It is possible that it doesn't work
on some operating systems.
Getting the size of a partition with -s might fail, if fdisk fails to guess the disk device, for the same reasons as with the previous bug.
SEE ALSO mkfs(8), cfdisk(8), parted(8) The fdisk program is fully documented in the info(1) format GNU fdisk User Manual manual.
