I have an iSCSI device that is large, ~17TB usable, and I've created an XFS file system at the device level. I mount the device no problem and am able to touch and remove files without issue. I start my application and within about 5-10 minutes I start seeing the following entries appear in /var/log/messages

I'm wondering if there is a way to shrink an ext3 LV mount as / .I tried to with resize2fs ... but seems that isn't possible if the partition is mounted.
View 8 Replies View RelatedDoes anyone have any good articles on mounting a Ubuntu volume as an iSCSI share on a windows box? Originally I was just going to use a SAMBA share but it turns out samba has issues with my lan security. So I thought since all I really want to do is create the share on my backup server that an iSCSI device would do. Been using the following article with limited success... [URL]
View 2 Replies View RelatedI 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.
View 1 Replies View RelatedThe first server I installed installed fine. The second server, installed with the same config, went to "kernel panic not syncing no init found try passing init= option in kernel" error. I tried reinstalling but it keeps going to that error after install reboot. The storage is ISCSI connected via Intel Server Adapter, which allows it to boot from ISCSI. Not sure if that's the cause for the problem, but the first server is connected to the same ISCSI and installed just fine.
Is there a way that I can make sure ISCSI module installs during installation? Although I think it is installed since it's able to copy the files and setup /dev/sda. I just wana make sure that it installs during setup.
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?

View 8 Replies View RelatedI have v 10.10 running the following (and I still have no idea how I got this all working). Myth, Squeeze server, X10 control system for the house, Virtualbox (where I run some windows stuff) and a general file and print service. It has 5 disk drives attached
1 - system disk
5- external usb to back up data to
2,3,4 - 2 tb drives in a raid config
I just restarted the server and the raid volume has not mounted. I looked in the webmin interface and the device is there but it doesn't seem to have the partitions attached. Again in webmin, the partitions seem to be on each of the drives. I used crash-plan to back up the data and music, but not the video, so I would prefer not to have to rebuild the lot if I don't have to. I really don't want to re build the lot out of my lack of experience with Linux. Is there an easy (ish) way of putting the raid back together to see if it's just dropped its config and the data is in tact (or can be rebuild from two of the three drives).
I seem to get logged into the NetApp filer fine - it shows the session, but I don't get a device. And don't panic - the system is CentOS 5.4, but the system is named OpenVMS (don't ask . . . ) iscsiadm shows me logged into the NetApp and the session is up.

I am trying to create a link to my windows xp workgroup where all my data is stored (I was surprised that linux could even see it!) I mounted a volume on the desktop apparently... that worked fine until I rebooted and it had disappeared. it was fairly annoying that I had to go back into the network and re-mount the volume. How can I get it to stay put, even after rebooting?

I have recently installed Debian on my NAS server. I have also configured Samba for sharing the home directory of a nas user i.e. /home/nas To this directory I have read/write from a windows machine using the nas user credentials.
When I mount my RAID partition /dev/md0p1 to the /home/nas directory, I then realize that all content in this directory (files and subfolders) is only owned by the root user. When trying to access from the windows machine the /home/nas directory, I do not have any write access, only read. I have tried both the nas and the root user credentials.
I have also attempted the change the ownership of the mounted RAID partition to the nas user with the -R recursive option, but I get for the internal files/subfolders an error "operation not supported".
How can I overcome this problem?
- Is there something not done properly in the /dev/md0 array definition (i.e. ARRAY /dev/md0 level=raid1 num-devices=2 UUID=bddf8b69:c97967b5:cb104784:7fef7cc3 )?
- Is there something not done properly in the /dev/md0p1 mounting (i.e. mount /dev/md0p1 /home/nas)?
- Should I do any extra configuration before the mounting etc?

I have mounted samba volume and I need to have write permissions for every new folder that's being created (currently, by default, on every newly created folder i have only read and execute permissions).I tried changing umask, but with no effect on mounted folder, umask changed only for local filesystem. I tried mounting with umask option, but with no effect again.I'm using ArchLinux on this machine, and I installed samba using default package manager (pacman).
View 1 Replies View RelatedI'm running 10.04 server on a Mac G5 with 2 network interfaces, one pointing to my network (192.168.0.x) and the other to a local partner network (192.9.100.x) with which we share a network volume to give/take PDF files.My client environment is MAC OS X (from 10.4 to 10.6) and until now only one client (with 2 nics) was connected to that volume: we don't have layer3 switches to do static routes over the two networks, so I decided to use my Ubuntu Server Mac to do this (it's also my new syslog server...).
Nics are configured correctly, and the local share (192.168.0.x) is well seen by everybody.But, when I mount the remote volume (192.9.100.x) to THAT shared folder, nobody is able to connect to the samba share (that now lists the remote volume directory...). The MAC OS X tells "unable to unmount the volume". IP forwarding is also activated on /etc/sysctl.confHere is a part of my smb.conf file

I built a CentOS 5 Linux cluster with GFS storage using local RAID volume and share it with gnbd_export/import on two web-servers. Now I need to expand that storage to another servers local volume. I saw the picture in the manual, but I don`t know, how can I create that scheme.
I can use gnbd_export on the second server and gnbd_import on the first. In that case I will have two volumes on the first storage and I can expand volume group, logical volume, etc on it.
What is the correct way to allow two servers to use the same file system on a SAN using iSCSI?Is it GFS on the two servers?
View 3 Replies View RelatedI have a server wich is connected to an iSCSI storage and gets harddisks from this storage. Sometimes I have to add new disks to this server. Everytime I add a disk and make an /etc/init.d/iscsi restart on the server the disks don't have the same device name as before the iscsi restart.
It should be possible to gave the disks persistent names using udev rules. Now I tried to create different rules in "/etc/udev/rules.d/99-static-iscsi-names.rules" e.g.
# /dev/sdc

View 1 Replies View RelatedWe 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.
I have a system with a 2TB RAID level 1 installed (2 x 2TB drives, configured as RAID1 through the BIOS). I installed Centos 5.5 and it runs fine. I now added another 2x2TB drives and configured them as RAID1 through the BIOS.
How do I add this new RAID volume to the existing logical volume?

Recompiling ncpfs package not possible because error free source package ncpfs version 2.2.6 might not be availble.

I have some large volumes that I don't want to automatically be e2fsck'd when I reboot the server. Is it safe to change maximum mount count to -1 and check interval to 0 while a volume is mounted, or will that cause problems to the file system?
