Topic: Server no boot

[smnirosh]

After driver update server not booting.
Giving me a message
Mount wrong fs type
Kernel panic - not syncing :attempting to kill init.
Pid: comm: init tainted

What can i do next to reboot to os?

[Jean-Philippe Pialasse]

by driver update, were you referring to kernel update ?
are you able to boot on the previous kernel ?

a little more information on this server would be helpful to help you  :
- hardware or virtual machine ?



if virtual machine and previous kernel still work, please change the type of CPU in the setting of the VM. This is a common  bug referenced against CentOS and last kernels. Google will answer the question quite easily.

[smnirosh]

It’s not a virtual machine. It’s our gateway server. I cannot boot to previous kernel

[Stefano]

ok, please describe at your best what did you do and what do you mean with "driver update"

[smnirosh]

Indownloaded a rpm file and ran it from hp driver update site. It was the driver for smart array controller. After reboot I couldn’t get into the system. Errro is
Mount wrong file type bad superblock on /dev/sdb2
The server configured as hardware raid(raid1).
Thanks

[ReetP]

I downloaded a rpm file and ran it from hp driver update site. It was the driver for smart array controller.

Why? Was there an earlier version installed or were you just playing about?

[smnirosh]

No I didn’t install it when we install sme server. Then i decided to install today.

[ReetP]

No I didn’t install it when we install sme server. Then i decided to install today.

No testing first then? Which 'drivers' did you get?

You will probably need a rescue disk and try to unpick the damage. I would guess that SME recognised the 'single' hardware drive presented to it, but the software driver is accessing the actual drives directly.

I presume you have a good backup ?

[Jean-Philippe Pialasse]

any backup ?
easy way would be to restore them


harder way would be to boot on installation media on rescue mode, chroot, uninstall rpm and reboot.

[smnirosh]

Yes i have a good backup. And a rescue disk. But i test this installation on our old server. No errors were found.
That’s why i took so much of time to update. It’s almost 5 months gone after installed sme 9.2. To new server.

[Stefano]

sorry but..
you're telling us you have an HP server with a smartarray controller.. did you setup hw raid when you installed SME or what?
and (forgive me, it's hard for me to believe) you installed a rpm today for that controller? why? did you have any issue? anything to be solved?
are you really telling us you installed it on your production gateway with no reason?

[smnirosh]

Yes we have hp server.
I installed bcos there was an error everytime it boots about smart array. I thought to install drivers step by step. Look this step😞😞😞. At the first effort i was failed.

[smnirosh]

I setup hdwre raid when i install sme server.

[Stefano]

Yes we have hp server.
I installed bcos there was an error everytime it boots about smart array. I thought to install drivers step by step. Look this step😞😞😞. At the first effort i was failed.

well.. which error?
was it at POST time or during SME's boot?
why didn't you ask for help here before doing it (in the general discussion area, for example)?

[smnirosh]

Now rpm - e command doesn’t recognize any packages i installed. I only remember first letter of this package. “hpvsa”. I put rpm -e hpvsa*

[smnirosh]

I check first with our old server before i deploy it without no error. I followed hp’s short explanations but no error detective processes.

[Stefano]

please, give us more details? from which shell are you trying to remove that rpm?
remember we can't see your monitor, so please be verbose

[Stefano]

your best bet is to reinstall from scratch and restore from backup; trying to make it work again could just be a loss of time

[smnirosh]

reinstall from scratch means ?

[Stefano]

insert SME's cd into your server and reinstall, do a new installation.. then restore your backup

[smnirosh]

now i checked with gparted of rescue linux disk.
sda1 - has data
sda2 - unallocated
sdb1 - has data
sdb2 - has data

i thing raid is not synced perfectly. Would it be a chance for us or is it useless clue?

[Stefano]

the last one..
you said you've an HW raid.. it seems that your rescue disk can't see it and so just see your 2 hds..

you're loosing time, believe me

[Jean-Philippe Pialasse]

check history

history|grep -i hpvsa

[Stefano]

check history

history|grep -i hpvsa

if he can't mount the original fs and chroot in it, he won't get any result

[ReetP]

Completely.

OP said:

The server configured as hardware raid(raid1).

That's not what he is seeing now.

Have you touched anything in the BIOS for the RAID card ?

[ReetP]

Ahhhh

https://support.hpe.com/hpsc/doc/public/display?sp4ts.oid=null&docLocale=en_US&docId=emr_na-c04422545

So, don't use this driver unless you do it at install.

(I just had a quick search at HP for 'hpvsa')

[Stefano]

doh..

reinstall and restore
good luck

[smnirosh]

no touch any settings. just installed the driver.
I loaded gparted GUI and it allowed me to select my two hdd drives. 500GB and 500GB i could able to see.

[Stefano]

Again, you won't solve your problems

[smnirosh]

Ok I am goint to reinstall the system. I have a workstation backup saved. What kind of data and settings will have been restored when i restore from backup?

[Stefano]

All, users, groups, data
All but contribs (but their conf will be restored)

[smnirosh]

ok good to know. what about openvpn?
and which file do i have to copy to usb hard disk to restore data (the backup done by workstation backup)?

[Stefano]

Read the fine documentation, really
Thank you

[smnirosh]

Ok thanks

[smnirosh]

I configured workstation backup on new server. But after few minutes it said error reading. The restore process stopped. 🤔🤔🤔

[Stefano]

anything useful in the logs?

[smnirosh]

Ok i will update. I ran once again the restore. Let’s see

[smnirosh]

I directly selected the latest incremental backup. Do i have to select the full backup instead? 🤔🤔🤔

[smnirosh]

This time “unable to retrieve http://localhost/server-manager. Error reading from socket

[Stefano]

how much data?

[smnirosh]

Little bit. Only primary ibay and in messege log it’s said “canonicalize m_connect_path failed for service (username and path)

[Stefano]

did you use the ip or the hostname to connect to the backup host?

[smnirosh]

I used ip.

[Stefano]

well.. something's wrong with IP or credentials

[smnirosh]

 I used the credentials of nas drive in the server manager.
