Restore Root Filesystem - Remote Tape?

Hi there,
Does anyone know of a way to restore a root fs from
a remote tape drive? The usual method seems to be to boot into single user mode off the cd but obviously you don't get the network this way.
Is the only viable way to have the tape connected directly?
Any ideas would be appreciated,
Thanks in advance.

The usual method seems to be to
boot into single user mode off the cd Yep.
but obviously you don't get the network this way. Why not?
I'm sure the (GUI) installer on the Solaris Installation CD will
configure the network interfaces and naming services first,
before the installation starts.
After that step has completed, you could start a terminal window
and there should be a usable network configuration, for restoring
from a remove tape drive.
With a rarpd and bootparam server on the same ethernet
segment, the configuration of the network interface should
even happen automatic.
And if all else fails, it shouldn't be too complicated to "ifconfig plumb" the network interface, manually configure the ip address,
then use the network:
ifconfig dnet0 plumb
ifconfig dnet0 inet 192.168.1.2 up
rsh -n 192.168.1.3 dd if=/dev/rmt/0 bs=32k | ufsrestore -xf -

Ufsrestore root filesystem from remote tape drive

If disk is replaced and I want to restore root filesystem, should I be able to access a remote tape drive to do this?
i.e when I do
boot cdrom -s, should I be able to access the nework? Or is that not posible with root filesystem installed?

Well, when you boot a machine into single user mode from a CD or DVD, it will not automatically configure the network, but you can do this by using normal ifconfig commands.
Before doing the restore you will have to create a new filesystem on the disk by runnings newfs and then mount it as /a or similar .
You can perform an ufsrestore from a remote machine by specifying the remote machines tape drive as the path to restore from, e.g.:
ufsrestore if <user>@<remote server>:<tape device>
for example, to do an interactive restore from a remote tape::
ufsrestore if admin@remote-server:/dev/rmt/1
.. one drawback with this is that ufsrestore probably rely on rsh to communicate with the remote server, so you might need to enable rsh and configure a .rhosts file for the user.
You can probably pipe the tape over ssh as well, with something such as:
ssh <user>@<remote-server> "dd if=/dev/rmt/1 ibs=1024" | (cd /a ; ufsrestore xf -)
.7/M.

Remote tape drive

I have system taht only has a tape drive attached to the SMC. Can you use a remote tape drive under solaris 10? do you nfs the tape drive? how do you connect to a remote tape drive?

Restoring the filesystems of the tape

Hi,
I am trying to build a sun machine off the image of another sun machine. I have created a backup of filesystems on the source machine of a tape that was created via ufsdump commands. Now I have to restore those filesystems to the destination system. The destination system partitions have enough space to accomodate the filesystems from the source system. The destination system already has an OS on it and can be wiped off.
Do I have to boot the destination system in a single-user mode with cdrom in order to do a ufsrestore of all the filesystems from the tape? If yes, how about non-root filesystems like /usr, /tmp, /var etc. Can they be restored in multi-user mode w/o bringing the system down. Any feedback in regard to this is appreciated.
Many Thanks,
ps

Did you figure out how to do that ? If not let me know and I will send you a procedure for that.

Kinit mounts root filesystem as read only [HELP][solved]

hello
I've being messing around with my mkinitcpio trying to optimize my boot speed, i removed some of the hooks at the beginning i couldn't boot, but then now i can boot but the root filesystem mounts as read only, i tried everything my fstab looks fine, / exists with defaults i tried to mount it referencing by it's uuid or by it's name and i get the same results, it mounts the filesystem as root only all the time no mather what i do.
There is not logs since i started playing with mkinitcpio, or anything i searched everywhere in this forum and around the internet, and i can't find any solution that would work, i restored all the hooks and modules on mkinitcpio and the result it's still the same. i also changed the menu.lst in grub to vga=773 but that's about it.
Can anyone help with this please i can't seem to boot properly.
Regards

Hello
Basically what happens it's that it loads all the uDev events then the loopback, it mounts the root read only, then when it checks filesystems it says
/dev/sda4: clean, 205184/481440 files, 1139604/1920356 blocks [fail]
************FILESYSTEM CHECK FAILED****************
* Please repair manually and reboot. Note that the root *
* file system is currently mounted read-only. To remount *
* it read-write: mount -n -o remount,rw / *
* When you exit the maintenance shell the will *
* reboot automatically. *
Now what bugs me its that i can do that mount -n -o remount,rw / with no problems and when i do
e2fsck -f /dev/sda4
it doesn't return any errors just says that 0.9 non continuous.
none of this makes sense to me!! thats why i though that the problem could be coming from mkinitcpio or something
any ideas
Thanks for your help, btw thanks for the quick reply
Regards

I set up nfs following the wiki. It works, but i can access the whole remote-root-filesystem, not just the nfs-root. Is https://wiki.archlinux.org/index.php/NFS up to date?

Thanks for the hints. Meanwhile, I have done some more background reading on running Arch in VMWare Player. In particular I followed the guidelines in this article. So it turns out that X requires some special configuration when run from within VMWare.
pacman -S xf86-input-vmmouse xf86-video-vmware xf86-video-vesa svga-dri
and a vmwgfx module is supposed to be loaded. I installed tha packages and tried to load vmwgfx, but when I do lsmod I just can't see it. Then it was pointed out to me that it might be a kernel mismatch problem. The linux installed on nfsroot is 3.6.2 whereas for some reason uname -a gives me version 3.5.6.
I've tried to rebuild initramfs with the new kernel using -k switch of mkinicpio, but it didn't help. It still boots into 3.5.6. It as if the initramfs from the client was taking precedence. So then I went back to the previous image of my VM, updated the system, made appropriate changes to mkinitcpio.conf and run mkinitcpio... and it no longer boots. mount: protocol not supported. I will post the details in my other topic.

Root filesystem

Can someone give me a best practice for increasing the root filesystem?

replayed wrote:
I did something stupid and screwed up the permissions in /Library and /Applications.
Long story short: I wanted to backup those directories before sending my MBP in for repairs. Rather than take the time to figure out Time Machine as an old Unix hand and newcomer to Mac OS X, I chose to use tar and cpio to backup those files from / that had been modified since my last OS install. Rookie mistake.
Having copied back those files and directories onto their former location, cpio lost all owner and group info, with everything winding up with owner root and group admin. Basic access permissions look preserved, but ACL info is presumably gone as well.
Surprisingly, my computer seems fine for the most part. A few applications complained about extensions, and I managed to quiet them by chgrp'ing a few .kext directories back to wheel.
But my latest software updates -- Safari 4.0.4 and Security Update 2009-006 -- are aborting while complaining about access issues with /.
I fired up Disk Utility and tried to Verify Disk Permissions, but the attempt fails immediately after announcing "Reading permissions database" with the error "The underlying task reported failure on exit."
I'm hoping to avoid a complete reinstall (of course), and I'm thinking I might get out of jail free if I can just manage to restore the correct ownership and permissions to the /Library/Receipts directory, which I understand is where canonical permissions are archived.
Am I on the right track here? Is there anything else I can do to restore permissions short of a full reinstall?
Any advice or suggestions would be appreciated.
honestly, I would reinstall in this situation. the permissions are too messed up at this point. that will be much quicker than anything else. an archive and install on top of your current system should fix things up.

UniPack / root filesystem on E10K running SC3.4 gets full

Hi !
The problem is within a domain in my E10K running sun cluster 3.4. I am running a CorDaptix application which is the electricity billing system developed by SPL World Group. This is a web based application.
My /root filesystem which sits on an internal Unipack disks 18GB on one of my domains gets full. I have moved the /opt and re-created it on an external disk. This has decreased my root filesystem but I can see that its filling up my volume again about 200MBs daily. When I check all my logs and find the files modified within the last days, I cannot find the cause.
Please, please help

process accounting should help clear up all the used space on the / partiton for now...
If you make a new /var partition, I'd wager you'll find a lot less instances of / filling up afterward..
Process accounting used to be something worthwhile if you didn't have a very busy system, but if you have a big honking database with many connections or a web server taking plenty of hits and doing subsequent system level processing (calling perl scripts and other things like that), you'll fill up the logfile system quickly.
Teamquest probably does a lot of new processes during it's monitoring and checking of your system health, so that would also contribute to things.
Bottom line, I agree, make a new /var partition, copy (via some methodology tar, cpio, ufsdump) from the original location to the new, and then edit the /etc/vfstab and put /var to mount on boot, and if you have the opportunity, reboot with the new /var (plus restored /var/sadm area), and you should be in good shape

First run it, without any modification to learn how it works. Check if works. Modify as you need. Check if works...
Do not worry about the mkinitcpio error, because such initramfs images should not be used for boot live medium. You can see that profiles uses own mkinitcpio.conf with at least archiso hook
Running mkarchiso directly is not the right way, at least if you do not know how things works.

Using ssh to do remote tape backup

I tried to setup a remote tape backup from ServerA to ServerB. The Tape drive is attached to ServerB. I had looked up some document how to setup "no password" login for root using ssh. Both servers had exchange their root public key.
When I tried the command "ssh ServerA ls" from ServerB, it showed me the ls of the "/". I was also able to do the same thing from ServerA.
However, it gave me access deny when I tried to do the following backup command from ServerA
ssh ServerB "/usr/sbin/ufsdump 0uf ServerB:/dev/rmt/0un /dev/rdsk/c0d0t0s0"
Can someone tell me what I had missed in setup the ssh, or is there any problem in the backup command. In my mind I just treated the ssh as rsh when I issued the backup command.
Thanks in advance.

as i understand it, you are trying to dump the /dev/rdsk/c0d0t0s0 from serverA onto the /dev/rmt0un on serverB, right?
hmm, not sure ufsdump has the facility to use ssh. in any case...
**NOTE -- not generally a good idea to allow a password-less login for anybody, even root from another machine; a better way would be to install sudo on the remote machine, and allow a user to be logged into without a password, but only allow that user to run a specific command as root. look up use of ssh "authorized_keys" file for more information on limiting command usage by key...
ok. so you have data on serverA, and you're going to put it on serverB... we'll start with simple. here's a tar command to copy all the files from serverA:/backmeup to serverB:/storeme; i'll use the prompt "serverA>" to signify that we're typing these commands from serverA.
serverA> cd /backmeup
serverA> tar cvf - . | ssh serverB "cd /storeme; tar xvf -"
now, you COULD use that to copy files directly onto tape...
serverA> cd /backmeup
serverA> tar cvf - . | ssh serverB "dd of=/dev/rmt/0"
you may have to play with the block size tho. for that matter, i would THINK that you could do the same for you ufsdump command:
serverA> ufsdump 0uf - /dev/rdsk/c0d0t0s0 | ssh serverB "dd of=/dev/rmt/0un"

[SOLVED] df -h does not reflect true root filesystem size

Why does df -h show root filesystem as being only 20G?
df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/cryptroot 20G 15G 4.6G 76% /
dev 7.7G 0 7.7G 0% /dev
run 7.7G 668K 7.7G 1% /run
tmpfs 7.7G 70M 7.7G 1% /dev/shm
tmpfs 7.7G 0 7.7G 0% /sys/fs/cgroup
tmpfs 7.7G 224K 7.7G 1% /tmp
/dev/sda1 239M 40M 183M 18% /boot
tmpfs 1.6G 8.0K 1.6G 1% /run/user/1000
That is what my df -h output looks like. My setup is full disk encryption using dm-crypt with LUKS, per the guide on arch wiki. I basically created one /boot partition and left the rest of the disk to be an encrypted partition for the root filesystem. So why is my system complaining about (and acting as if it's running out of space)? Have I forgotten something?
Thank you for reading this. Let me know if you need any more logs or info on my setup - I realise I haven't provided very much info here, but I can't think of what to provide.

And graysky: I thought I made the partition for /boot 250 MB and the encrypted partition 465.5 GB but I'm now quite sure I did something wrong...
Thank you all

After upgrading to Solaris 10 "Can't load the root filesystem" on V245

I have a Sunfire V245 that was running on Solaris 9 (very stable). I upgraded to Solaris 10 (6/06) this morning and everything seemed to go smoothly. After the upgrade the system rebooted, but will not boot. I get the following uptput;
Rebooting with command: boot
Boot device: disk File and args:
SunOS Release 5.10 Version Generic_118833-17 64-bit

pxb_bcm: cannot load driver
Cannot load drivers for /pci@1e,600000/pci@0/pci@a/pci@0/pci@8/scsi@1/disk@0,0:a
Can't load the root filesystem
Type 'go' to resume
"go" attempts to reboot, but I end up back in the same place.
Please help.
Thanks in advanced,

It seems like the driver for that device does not exist. Since the system installed successfully it means that it S10 did find a disk. I wonder if that was a different disk than the default disk. Please boot to the miniroot and check the disk info.

Moving root filesystem to another hard drive

Hi everyone,
I've been using Arch Linux for a few months now and it is by far my favorite Linux distribution.
I currently have Arch on an old Pentium III, with a whopping 20 GB IDE hard drive.
I'm building a new computer, and want to use a larger 160 GB SATA hard drive, and I was wondering what is the best way that I can just transfer my entire root filesystem so I don't have to bother copying all the scripts, programs, etc.
Can I just tarball my root directory, partition my new hard drive, and use some other LiveCD to copy the root partition? I know this shouldn't be that difficult, because everything in the root partition is in /, unlike Windows, which has association problems with the registry.
Thanks!

I'd never want to lead anyone down the garden path without at least trying this myself so for the last hour or so I've done just as described above on an old computer I have that I play around with and a spare small 8 gb hard drive. I first tried copying the files over with thunar but that didn't work too well (froze up) probably due to trying to copy /sys and /proc--duh.
I tried again using midnight commander (to install do #pacman -S mc) and it worked perfectly. The /dev directory copied over just fine but don't try copying /proc and /sys. Just make empty directories so the system can put what it needs there. Also just make an empty /mnt directory and put your devices in later--otherwise I'm not sure what would happen if you were copying your /mnt/newroot to itself, but I'm sure it wouldn't be good.
I tried to just install grub on the slave with #grub-install /dev/sdb and it said it installed fine but when I switched the slave to master and disconnected the old master, grub wouldn't boot (probably because it was installed to /dev/sdb?) so I had to use the arch install disk to install grub. Then, much to my surprise--like I had any doubts--I rebooted and now I'm posting this with the newly copied Arch with xfce4.
It might not be a bad idea to backup any really important stuff but you are just copying and unless you do something silly, everything should work fine.
