Ubuntu :: Can't Get ISCSI Initiator Start After A Reboot
Oct 19, 2010
I 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 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.

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.

I am trying to connect the one of server RHEL5.4 to the IBM iSCSI storage. Server is equipped with 2 single port Qlogic iSCSI HBA(TOE). RHEL detected the HBA and installed driver itself (qla3XXX). I have configured the HBA ip address in the range of iSCSI host port of storage. Both of the HBA is connecting to the two different controller of storage. I have discovered the storage using command iscsiadm -m discovery command for both of the controller and it went through fine. But problem is whenever server is restarting if both of the hba is connected to the storage then server will not detect the volumes which is mapped to the server and then to detect the volume I need to run "mppBusRescan" and "vgscan" command each time. If only one path is connected it is fine.

We have a Centos 5.6 server mounting two iSCSI volumes from an HP P2000 storage array. Multipathd is also running, and this has been working well for the few months we have been using it. The two volumes presented to the server were created in LVM, and worked without problem.We had a requirement to reboot the server, and now the iSCSI volumes will no longer mount. From what I can tell, the iSCSI connection is working ok, as I can see the correct sessions, and if I run 'fdisk -l' I can see the iSCSI block devices, but the O/S isn't seeing the filesystems. Any LVM command does not show the volumes at all, and 'vgchange -a y' only lists the local boot volume, not the iSCSI volumes. My concern is that, the output of 'fdisk -l' says 'Disk /dev/xxx doesn't contain a valid partition table' for all the iSCSI devices. Research shows that performing the vgchange -a y command should automatically mount any VG's that aren't showing, but it doesn't work.
There's a lot of data on these iSCSI volumes, and I'm no LVM expert. I've read that some have had problems where LVM starts before iSCSI and things get a bit messed up, but I don't know if this is the case here (I can't tell), but if there's a way of switching this round that might help, I'm prepared to give it a go.There was absolutely no indication there were any problems with these volumes, so corruption is highly unlikely.

was able to install iSCSI target via yum, configured a couple of target LUNs, in fact all the same steps that worked on Fedora 10 appeared identical. However, when I try to start the service the following happens.
[root@Server01 ~]# service iscsi-target start
Starting iSCSI target service: FATAL: Error inserting crc32c_intel (/lib/modules/2.6.29.4-167.fc11.i686.PAE/kernel/arch/x86/crypto/crc32c-intel.ko): No such device

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 had recently setup an OpenVPN server on x64 10.04 via the guide found at: [url]
Everything was working perfectly, all clients were able to connect etc.
Today I needed to reboot for a completely unrelated issue - only to find that upon logging in, openVPN was no longer running.
When I tried to execute 'sudo /etc/init.d/openvpn start' I'm presented with an interesting message...
This *used* to say Server. I've double checked all the configs and scripts used in the config and they all check out OK. I purged and reinstalled openVPN to no avail...

Everytime i start my computer, proxy server (with transparent proxy) wont start at first boot. It produces an error when i tried to start it manually (from webmin).
Code:
2010/05/05 05:51:58| parseConfigFile: squid.conf:4970 unrecognized: 'httpd_accel_host'
2010/05/05 05:51:58| parseConfigFile: squid.conf:4971 unrecognized: 'httpd_accel_port'
2010/05/05 05:51:58| parseConfigFile: squid.conf:4972 unrecognized: 'httpd_accel_with_proxy'
2010/05/05 05:51:58| parseConfigFile: squid.conf:4973 unrecognized: 'httpd_accel_uses_host_header'
Rebooting the computer fixed it.
Is there a way to make it work the first time i turn on my computer? Those errors, httpd_accel, i enter those manually in squid.conf.

I've scheduled a task in gnome-schedule to run at each reboot. When I click on "preview task" it initiates a one-time run just fine. However, after reboot it just doesn't want to start the task.

I urgently need expert assistance. During a cold-start reboot, something corrupted my / directory making it impossible to access much of anything. I was able to log into a recovery console and do "ls /" which shows most of the critical directories although "media" is missing. However attempting to "ls /home" gets the "no such file or directory" error message, as do attempts to ls most of the others. Doing "ls -l /" gets one item listed, followed by a single record out of /var/log/syslog, then nothing at all.
Attempting a normal login (I've disabled the quiet and splash options, so I see all the startup messages) gets to doing fsck on the swap partition, and that stalls out at 14% complete. The fsck on the root partition completed okay, apparently. This machine is my router, firewall, FTP server, and also hosts VirtualBox VMs that contain all of my customer support tools. The VMs themselves are partially backed up on another box, fortunately, but it took me a couple of months to get the failed box configured properly so if possible I need to recover it. For lack of space, I've never been able to do a full backup of it -- and permissions have foiled portions of all my other backup attempts on it.
Complicating matters is the fact that I have a moderately large data recovery job scheduled to arrive this evening (July 3) to be done while the customer's business is shut down for the holiday. Without the FTP server I'm unable to receive the files, which will total from 100 to 200 MB in all. Is it likely that testdisk may be able to rebuild the borked main root directory, if run from a live CD? The system is Hardy LTS 8.04.4, with 3 GB of RAM and a 250 GB SATA drive. I'm posting this from my WinXP laptop, which doesn't get along with my LAN so connects from a different router than the one that's down.

Ok so I followed the instructions here [url] and this works great for the install however if the machine is rebooted the VMWare server refuses to start back up stating that it knows that its installed but it was not installed with the right installer.
This is on a Dell Server I can't remember the model right now but its got Dual PIII in it. I'm running Ubuntu Server 32bit 10.10 on the box as well. Thank you in advance for your assistance with this. Once I get this first server figured out I'll get my other one fired back up.

Running close to a go live date of 11/10/10 and need to have this fixed. DBA is pointing to the OS which is RedHat Enterprise Release 5.3. with Oracle RAC 10G
Oracle works fine it just won�t start up automatically after a reboot. After a reboot a person with root access has to increase the number of semaphores and then oracle will start and function. The next time the machine is bounced the same issue will arise and the semaphores need to be increased again by hand. Every time the machine is bounces the semaphores need to be increased by hand. This is not normal for a Unix machine. Semaphores are not part of the oracle install, it is a kernel parameter on Unix machines. Eventually after several reboots the semaphore parameter will be too high for the box to function. Once the semaphores have hit their peak, we reset them back to the original value and the whole process starts over again. This is a Unix build issue that has only surfaced on the production machines. The DAS development machines have the exact same oracle build and do not have this issue.

I have installed FreeRadius to a Debian Linux server.
I have configured an account called Support to run the Radius as I didnt want Root to be the user to run this.
I want Radius to start up automatically after the system is rebooted but I don�t know how to do this. I am new to Linux so please bare with me. If the system is rebooted, is it possible for the Support account to be logged in automatically? Is there a script I can create to automatically login the Support account? This may not be secure but it has been requested. Also the main question is after a reboot can the Radius be configured to automatically start without the need for someone to login? So if the system is rebooted and then goes back to login prompt, can the Radius then be running?
I have had a good search about scripts but with my limited knowledge it isnt too easy.
So far Ive read it says to create a script in /etc/init.d which Ive done and named start-my-radius.sh I think Ive made It execuatable by chmod 777, if thats right?
The script looks like this:
But I dont know if thats even right? The radiusd is located in the /usr/local/sbin/ and the radacct and radius.log is located in / usr/local/var/log/radius
Some stuff I have read says it needs to link into /etc/rc.d but there isnt a rc.d directory, I have other rc directories which are rc1.d rc6.d.
After reading it also said something about using rc.radiusd which will automatically start Radius after a reboot, but again I cannot understand exactly what I need to do.
Let me know if I am on the right track? Will the start-my-radius.sh script work after the system is rebooted without someone actually login and how do I get it to work?

My problem now is that lsyncd does not automatically start if the server reboots. I need lsyncd to start automatically also using the --delay 5 option.
I've had trouble finding any info on this other that some Japanese sites (I cant read japanese) using chkconfig, although it didn't work as I think chkconfig is depreciated anyway.

We have three production websites running on RHEL 3 AS running tomcat 5. After a reboot last night Tomcat will not start and has the following in the catalina.out log:
Mar 20, 2011 4:09:31 PM org.apache.commons.digester.Digester startElement
SEVERE: Begin event threw error
java.lang.NoClassDefFoundError: org/apache/naming/resources/ProxyDirContext
at java.lang.Class.getDeclaredConstructors0(Native Method)
at java.lang.Class.privateGetDeclaredConstructors(Class.java:2389)
at java.lang.Class.getConstructor0(Class.java:2699)
at java.lang.Class.newInstance0(Class.java:326)
at java.lang.Class.newInstance(Class.java:308) .....
I have spoken with our Java Developers and they seem to think it is something up between httpd and tomcat at an OS level. Since Tomcat is not starting and giving an error that it is all ready running, I think you have a stale lock file. Look for the file /var/run/tomcat5.pid and cat or less it to see what the PID number is. If it matches the error, then delete the file and try to start Tomcat again. It should start this time.
Most common problem with Tomcat5. Try following :
1) Search PID in /tmp, if found delete it or else stop your tomcat.
2) Undeploy your application
3) Check out this link [URL] to know what causing tomcat to generate this error.
If none of them work then check your application configuration settings. [URL]. When I do start tomcat it appears to start:
[root@RPSI-2 san00]# service tomcat5 start
Starting tomcat5: Using CATALINA_BASE: /usr/share/tomcat5
Using CATALINA_HOME: /usr/share/tomcat5
Using CATALINA_TMPDIR: /usr/share/tomcat5/temp
Using JAVA_HOME: /usr/java/jdk1.6.0
[root@RPSI-2 san00]#
But then I try to find if it is running via ps -ef | grep tomcat5, I only receive my query. I perform the same query on Java and it also only returns my query.

Few days ago we had a server maintenance. The system was shutdown, we fix the CPU fan, and start the system again. But somehow when the system starts, our IMAP server - dovecot is not running. It just sit like a rock. Because the machine had a CPanel/WHM, I tried to restart dovecot using cpanel and got a message:
Code:
That was not really useful....
When I tried to restart dovecot using command line, I got nothing. really nothing.
Code:
How to find out what happens to my IMAP/dovecot? And anyway to make it run again?
I'm using CentOS 5.5 X64 with dovecot 1.2.16

Suddenly I noticed that all my file system had gone into read-only mode. My first thought was that the Sata data cable had got loose for one of the drives, but that wasn't it. All cables were connected correctly. So I booted up again, but I only came to a rescue mode terminal.
I have four software MD raid volumes:
Code:
Running mdadm -D on the volumes told me that the sdc drive had been kicked out from both md0 and md1. However, md3 had kicked out two drives, so I couldn't get any information from mdadm -D on that. For md0 and md1 I could just add the kicked-out partitions back into the volume, but for md3 I don't even know which partitions got kicked out...
Here are some outputs:
Before I rebooted the first time I saved the 200 last rows of dmesg to a memory stick. Here they are:
Code:
Trying to restart the md3 volume in the rescue mode terminal:
Commands:
Code:
Output:
Code:
The "Array State" row seems interesting. I guess that AAAA means all four drives are OK. But then why does the array state differ between the members?
Does anyone know how to figure out which two members that got kicked out? And how do I get them back in (assuming that they're OK)?
