I am still extremely green, but I have been able to add my Debian Wheezy server to my Windows domain and I am able to connect to my Windows file server iSCSI target, but it does not re-connect at system startup. The nodes are set to startup automatically and are in my fstab by UUID. However, checkin dmesg as well as the syslog shows that iSCSI doesn't attempt to initiate a connection at boot.
View 3 RepliesI am currently wanting to connect to an NAS unit that I have. I have installed open-iSCSI and have made the following changes to the iscsi_conf file:
Quote:
# To set a CHAP username and password for initiator
# authentication by the target(s), uncomment the following lines:
node.session.auth.username = "user"
node.session.auth.password = "12 digit pass"
[Code].....
My goal is to get the iSCSI initiator to connect after a reboot. Mounting after connecting I am sure this will be another challenge.
I have used open-iscsi for a couple of years on fedora and oracle linux, but since I use ubuntu for my desktop, web servers and mysql servers I thought I would be nice to do so on our new MySQL-server which should be connected to our Qlogic SAN. The installation went well after figuring out how to put two network cards on the same network, which seems to be the Qlogic way to do multipath. But I cannot make open-iscsi to log on automatically after reboot. Is there something different with open-iscsi on ubuntu?
Everything works if I logon and do:
iscsiadm -m node -l
multipath -v2
And then mount the volumes but if I try to put them in my fstab like:
/dev/MySQLdata/data/var/lib/mysql/ext4_netdev1 2
/dev/MySQLbackup/backup/var/mysqlbackupext4_netdev1 2
I have never done this before but stood up a new Debian (testing) x64 system. It only has 146GB available for RAID1 so I created a 500GB iSCSI LUN on my NAS device on the network and am really confused how I can attach my Debian to the iSCSI LUN I created. Right now the OS is installed all locally on the machine but I would like the iSCSI LUN to be the /home directory for mail storage. Is this possible or do I need to mount the LUN to a newly created folder / mount point that is locally attached?

I just used dd to clone a linux partition to a new hard drive, it had 800mb left on the old hard drive, after dd, new hard drive lists 1.29/1.3 terabytes full. Is this what happens by default in dd? How can I fix this?

It is not a resolution problem it just doesn't use the whole screen. Hopefully this explanation is understandable. On lenny i had the same issue but once i changed the console resolution size in grub everything was fine. Sadly this is not the case with squeeze.

I'm trying to install Debian 6.0.1a on a MacBookPro5,5 (intel core 2 duo - EFI firmware). I have rEFIt 0.14 and a live cd of Debian (on a usb stick). I'm installing Debian on a usb stick. The installation process goes along smoothly, but then, it's impossible to boot up the freshly installed system (I get a black screen with a blinking cursor). I read that this is a common problem but all the solutions I have found have not worked for me.
The underlying idea is that since Macs have EFI firmware instead of a BIOS, the partition tables of devices are different (GPT for EFI versus MBR for BIOS), and grub is incompatible with GPT (I know there is an EFI version of grub but it is said to not work well). So the devices must have both a GPT partition table and a MBR one. These have to be "synced".
The tools available for this are:
- rEFIt can sync the partitions, but I haven't managed to have it sync them on any other device than the main hardrive. If I sync the main hardrive, then even the live cd (which is on a usb stick) won't boot (black screen with "GRUB _").
- Debian has a tool called gptsync, which returns a message saying "no data partition in gpt table, nothing to sync".
- Mac OS X has a tool called gptsync which returns a message saying "unknown partition type detected - I'm not touching this disc".
The reason there is no data partition is that gptsync sees my main partition as "EFI system". If I could change that, maybe I could sync the partition tables. Can that be done? Also, something I don't understand is: the live cd boots fine without grub. So why do I need grub? Couldn't the system boot up without it like the live cd does?
I just recently installed Lenny 5.04 on my computer and when it comes to the desktop the top and bottom bars seem to be set for a lower resolution. They only go about a third of the way across the screen and if set to be at the bottom the bottom bar is only a third of the way down the screen. The logon window fits this format but most other things go full screen (games don't though).
What is it I need to change and as an aside how do I change the screen resolution if I want everything bigger (so I can read it with my old eyes)

Creating a separate /tmp partition manually during install prevents a clean shutdown.
Setup: Debian 8 minimal server configuration (SSH only) using net install as virtual machine on Windows Server 2012 R2 Hyper-V (Gen 2).
1024 MB RAM, 20 GB VHDX, and 1 Processor, EFI boot
Packages installed: openssh-server, sudo, unattended-upgrades, bsd-mailx postfix
Application: IPv6 gateway using 6in4 tunnel
Symptoms: When shutting down the operating system (poweroff or reboot), the message
A start job is running for Unattended-Upgrades ( xx seconds / no limit ).is displayed on the console and will persist for several minutes before eventually timing out and shutting down.I've tried several different configurations. Any configuration that creates /tmp automatically (whole disk with single partition, or disk with separate /home, /var, and /tmp partitions) works fine and shuts down promptly. When I partition the disk manually (512 MB EFI Boot, 17 GB /, 3 GB /var, 512 MB /tmp, and 512+ swap) the problem occurs. I've narrowed it down to just the /tmp partition by testing and comparing various configurations (including/excluding partitions, placing partitions on a separate disk, changing the partition sizes, matching against automatic configurations, etc.).
I have also compared the /etc/fstab and /etc/default/tmpfs configuration file between working and non-working systems and cannot see any meaningful difference.
My system have 3 partition.
1) Windows ntfs.
2) distro ext4.
3) distro ext4.
When I clicked their partition, system request user or root pass. I need it without password like ubuntu or mint.

My mouse cursor cannot go past the last line "expressions can match many items, but evidently not everything ..."
If I scroll upward, I can copy the entire webpage.

Sometimes I come across fixes for linux issues on websites. I copy the information and email it to myself for future reference in case I have to reinstall the OS again. I can do a ctrl A and ctrl c but then the entire website is copied. The ads on the side, etc.
If I put my left mouse cursor on the first word in a thread and drag/highlight downwards, my mouse cursor stops line 35 on the page. If I do the same thing but backwards, my mouse cursor goes all the way up the page. This only happens on Firefox and Google Chrome. This doesnt' happen with mousepad, Libre writer or Libre calc.

I did a bit of reading and it seems that most people suggest using badblocks to first get a list of badblocks from the drive and save it to a file. Then use e2fsck to then mark the blocks listed in the badblocks file as bad on the hard drive. My problem here is that this drive is part of a RAID5 array that hosts my OS. I wanted to confirm if this was still the correct process.I boot to my Live Debian disk, stop the raid array if it's active. Then run badblocks + e2fsck commands on the drive in question and then reboot.
Found this 'Startup Disk Creator' in Ubuntu,it is useful,how we get it install in Debian Squeeze? There's a Unetbootin for Debian,but it pull in lots of qt stuff,I don't like it.

I have an iSCSI target on my Ubuntu 10.04 LTS server that is giving me access to 3 x 2TB volumes. I am using LVM to create 1 big volume and using it as a place for my backup software to write to. Upon initial setup I tested to see if the connection would still be there after a reboot, and it was. After going through the trouble of configuring my backup software (ZManda) and doing a few very large backups I had to reboot my SAN (OpenFiler) for hardware reasons. I took my server down while performing the maintenance and brought it back up only after the SAN work was done. Now, the LVM volume is listed as "not found" when booting.
Using iscsiadm I can see the target but LVM doesn't know of any volumes that exist using those targets. I need to get it back up and running and then troubleshoot the reboot issue.
