I changed machines to a raspberry pi. Could it be that when I assembled the array, I did it as raid 0 when it needed to be raid 1? The reason I ask this is because I see this from lsblk as in:
? Should i have been:
If I resamble it as a raid 1, will it destroy the data?
I created a RAID 5 array and when I list out the attributes of the "hdisk" it reports back raid_level = 5 but the RAID level of the array = false. What does this actually indicate about my array? I've never paid much attention to this until now since I have a disk reporting failure I want to make... (0 Replies)
Hi guys,

Hi Peeps,
Can anyone help me an EFI lablel on a 3510 raid array that I cannot get rid of, format -e and label just asks you if you want to label it. Want an SMI label writing to it.
Anyone got any ideas on how to remove the EFI label?
Thanks in advance

One of my very old drive farm servers had an OS fault and can't boot now but I'd like to restore some files from it. I tried booting Ubuntu from a CD, but it couldn't see the drives -- possibly because they're RAIDed together. Is there a good way to get at my files?

partx
PARTX(8) System Manager's Manual PARTX(8)NAME
partx - tell the Linux kernel about the presence and numbering of on-disk partitions
SYNOPSIS
partx [-a|-d|-s] [-t TYPE] [-n M:N] [-] disk
partx [-a|-d|-s] [-t TYPE] partition [disk]
DESCRIPTION
Given a device or disk-image, partx tries to parse the partition table and list its contents. It optionally adds or removes partitions.
The disk argument is optional when a partition argument is provided. To force scanning a partition as if it were a whole disk (for example
to list nested subpartitions), use the argument "-". For example:
partx --show - /dev/sda3
This will see sda3 as a whole-disk rather than a partition.
This is not an fdisk program -- adding and removing partitions does not change the disk, it just tells the kernel about the presence and
numbering of on-disk partitions.
OPTIONS -a, --add
Add the specified partitions, or read the disk and add all partitions.
-b, --bytes
Print the SIZE column in bytes rather than in human-readable format.
-d, --delete
Delete the specified partitions or all partitions.
-g, --noheadings
Do not print a header line.
-l, --list
List the partitions. Note that all numbers are in 512-byte sectors. This output format is DEPRECATED in favour of --show. Don't
use it in newly written scripts.
-o, --output list
Define the output columns to use for --show and --raw output. If no output arrangement is specified, then a default set is used.
Use --help to get list of all supported columns.
-r, --raw
Use the raw output format.
-s, --show
List the partitions. All numbers (except SIZE) are in 512-byte sectors. The output columns can be rearranged with the --output
option.
-t, --type type
Specify the partition table type -- aix, bsd, dos, gpt, mac, minix, sgi, solaris_x86, sun, ultrix or unixware.
-n, --nr M:N
Specify the range of partitions. For backward compatibility also the format <M-N> is supported. The range may contain negative
numbers, for example "--nr :-1" means the last partition, and "--nr -2:-1" means the last two partitions. Supported range specifi-
cations are:
<M> Specifies just one partition (e.g. --nr 3).
<M:> Specifies lower limit only (e.g. --nr 2:).
<:N> Specifies upper limit only (e.g. --nr :4).
<M:N> or <M-N> Specifies lower and upper limits (e.g. --nr 2:4).
EXAMPLES
partx --show /dev/sdb3
partx --show --nr 3 /dev/sdb
partx --show /dev/sdb3 /dev/sdb
All three commands list partition 3 of /dev/sdb.
partx --show - /dev/sdb3
Lists all subpartitions on /dev/sdb3 (the device is used as whole-disk).
partx -o START -g --nr 3 /dev/sdb
Prints the start sector of partition 5 on /dev/sda without header.
partx -o SECTORS,SIZE /dev/sda5 /dev/sda
Lists the length in sectors and human-readable size of partition 5 on /dev/sda.
partx --add --nr 3:5 /dev/sdd
Adds all available partitions from 3 to 5 (inclusive) on /dev/sdd.
partx -d --nr :-1 /dev/sdd
Removes the last partition on /dev/sdd.
