Can Ubuntu Read Xfs From Nas Drive

JustTrying · Feb 14, 2016 23 0 4,510 0

Hi anybody,
establish a possible solution here to gain access to my one-time nas-drive (the nas obviously died) by using an Ubuntu live cd. Tried to do then, but when accessing the bulldoze I get the message: "Y'all have no rights to access this drive..."
(Using the nas I tin can however see the users, but non the folders anymore, then I wait the nas is gone.)
No repair utility or something of the kind.
Does anyone have i or more ideas how to get access to the drive over again and get to the data?
Difficult to get info nearly 'the day after....' the nas died.
Thanks for whatsoever help in advance.

md127 has sdb3 open so you lot need to clear md127 first: sudo mdadm -S /dev/md127

More info is needed to help you. How are y'all accessing the drive? Are you running every bit root? What kind of NAS device do you take? Post the output of... cat /proc/mdstat

Cheers for your aid - will endeavor to detect more answers.
Here is what I can say now:
Dual Bay Nas-server. Brand unknown. The service doesn't exist anymore (unisupport.net in Denmark), the website is for sale.
Had 3 years of garantee, this is twelvemonth # 4.
The tool to access the nas is NetTool.exe.
The 2 drives have been formatted to XFS.
Set up via web-based direction.
Did use the nas nether a win2k pc and an old laptop. That w2k-motorcar died ii months ago, so I have built a new pc with legal win7.
The laptop was that old and having so many problems that I have bought me a simple new one, with win8 pre-installed.
Cannot meet anything on the raid-disks (continued via sata inside the new pc) with win7.
Following the suggestion somewhere here, I did create an iso disk with Ubuntu 14.04.3.
I am not (yet) a Linux experienced person, and so ran the live cd and tried to get to the files on the disk.
In Ubuntu I could see the disk and a few directories. Entering any of them gave me the info that I had no rights to become in.
Not sure if I ran Ubuntu every bit root. No thought if a simple user of a live cd has any admin rights or non.
The problem is I practise not know which program/system stopped me.
Was information technology Ubuntu? Was is the nas-drive?
Can I make a user with admin rights when running a live cd?
I exercise know the user proper noun and the password for the nas.
If Ubuntu allows me to, I tin create a user with the name of the administrator and give that user the password that I used for the nas.

I do take a backup of the nas from 1 week earlier the nas stopped working.
Created that backup with win7, via the network. Just copying all the stuf.
The basic problem is that my administration data (I am a small trader -an artist- and demand that administration for the tax submittance) from the moment betwixt the backup and the end of the nas-life is non on a backup. Could enter the data one time more, only then a bunch of assistants numbers will be gone. Non funny for taxation employees...

Will try to run the live cd once more shortly.
Suggestions on what to try by then are much appreciated. Will look for cat/ proc/mdstat, whatsoever that may be. I will find it.
Thank y'all in advance.

Just an extra bit of info: the nas was a stand up-lone machine, stored far abroad from the pc'southward at home, for safety reasons.
Continued via network cable.
It was non a built-in nas, within my pc.
Excuse me for not mentioning.

Username root is the super user and gives y'all full permissions. See commands id and sudo. Notation best practice is to make drive images and execute recovery operations on the images to guard against mistakes. See command ddrescue. As the filesystem is XFS information technology's likely that Linux Software RAID was used by your NAS. Encounter control mdadm. When yous run command "cat /proc/mdstat" it shows the condition of your mdadm RAID. But without a basic understanding of Linux it volition exist a challenge for you to recover the Linux way. I advise you first try Windows recovery tools such every bit R-Studio or UFSexplorer which will be safer and easier for you to use.

@ S Haran - Yes, understand what you are proverb. But I practise want to get for the linux way. Information technology will take a couple of days for me to get into this stuff. Already studied basic info. Not afraid of a command line, that's the way I started in 1985

Windows had to be invented at that fourth dimension I think. Norton Commander, lots of printer problems and that kind of stuf.

Like to install an extra drive (for 64bit o/s and for linux installation) and rebuild the nas; the nas-drives are out at present.
Are both drives of a raid-1 absolutely completely identic, or has one of the two some kind of database/fat/whatsoever?
I mean, does it brand a difference the manner I put both drives back into the nas? Both drives are identical and I haven't found any identification which i of them should exist placed in which slot. Well, may equally well try and see what happens.
Effort to create an iso of both drives; sounds a good thought.
You will hear from me in a few days; after the weekend I hope.
Enjoy life.

Still busy trying to have Ubuntu do what I similar it to do.
Tin can even so access the nas via http://ip-address.
Seems to exist a chance to make a backup, but non clear yet how to deal with that in Ubuntu - having problems with user rights.
Will exist back - cheers for your patience.

Back once again. Studying the human pages peculiarly for the commands mentioned here.
It is a compassion I have non been able to find more info (yet) about dealing with a harddrive that comes out of an external nas. Many time I read near files on the local deejay where ubuntu resides. These files practise non exist in my instance, which makes understanding a bit confusing.
result for the question before:

joes@film16-linux:~$ sudo cat /proc/mdstat
[sudo] password for joes:
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md127 : inactive sda3[0](Southward)
976486848 blocks

Working on creating a backup. Fear to accept written anything to disk, so studying many man pages. What a pleasance to get that much basic info. Not easy to abound in, just not impossible either.

Double Commander shows the drive with 'md127' and states 'disk is not available'.
Information technology shows a partition as sda2 after the md127.
In sda2 there is a raidconf file stating:

[RAID]
raid_enable = ane
raid_mode = i
disk_num = two
disk1 = "/dev/sda"
disk2 = "/dev/sdb"
disk3 = ""
disk4 = ""
fstype = 0
raid_vendor = ""

Think this partitioning is on the nas-deejay. See if I can get more info.

Your /proc/mdstat says that sda3 is a fellow member of md127. Where did it become?

In whatsoever case see if y'all can find your data with: sudo tetdisk /dev/sda

remark: the /dev/sda is a rather pocket-size ssd disk that I use for swapfiles to speed things up - not office of the array deejay.

So information technology looks like sdb3 is now your RAID sectionalization. Post: sudo mdadm -E /dev/sdb3

Y'all might want to experiment with testdisk to recover a spare drive to become an idea how information technology operates.

Did a new mdstat:
joes@film16-linux:~$ cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md127 : inactive sdb3[0](S)
976486848 blocks

medico 127 is now an inactive sdb3 instead of sdba
the number of blocks is the same as in the first mdsat: 976486848 blocks
Perhaps had a hickup...
But this shows that sda is not the one, as I already thought.

It looks like testdisk is not (yet) set up for reading xfs ?

That looks better. And then now you lot could try: mdadm --assemble --force /dev/md0 /dev/sdb3
