hi All, thanks for the responses. After being dropped into the # Filesystem repair prompt, ( on account of "inode 27344909 has illegal blocks" ) following warm reboot (via "reboot") after finding (SAN ) filesystem in read-only mode yesterday morning (possibly because of HBA fault on SAN) , I ran fsck -r /data (Linux version 2.6.18-92.1.18.el5 , Red Hat 4.1.2-42 , ext3

I came across an old post comment yesterday (from http://echenh.blogspot.com/2010/04/how-to-extend-lvm-on-vmware-guest-os.html ) discussing the "hack" of LVM on Linux VM guests and whether it's better not to use it to simplify disk management. I've re-posted the comment below, does it sound reasonable? Is it better to not use LVM on Linux VM guests? --Russell

Hello, Today a virtual server under my administration ran out of disk space, so I had to get extra space to it.. while it was running, because it's an important web server without any kind of HA/Load Balancing (don't do that, kids). So what happened, is that after another administrator had extended the disk from VMWare, I tried to extend it from the OS side. Everything went well,

Greetings all, I am in need of professional insight. I have a 2 node cluster running CentOS, mysql, apache, etc. I have on each system a fiber HBA connected to a fiber SAN. Each system shows the devices sdb and sdc for each of the connections on the HBA. I have sdc1 mounted on both machines as /quorum. When I right to the /quorum from one of the nodes, the file doesn't show up on the

Hi there, I am very new in linux and met the filesystem problem as described in the following, I tried to use 'fsck' and tried to find some support documents but failed. Your hints and helps are very appreciated. Millions of thanks, Annie The error message is (sorry for it's length, I just want to make it clear) ====================================================================

Maybe one of you has experienced something like this before. I have a host running CentOS5.3, x86_64 version with the standard qla2xxx driver. Both ports are recognized and show output in dmesg but they never find my storage device: qla2xxx 0000:07:00.1: LIP reset occured (f700). qla2xxx 0000:07:00.1: LIP occured (f700). qla2xxx 0000:07:00.1: LIP reset occured (f7f7). qla2xxx 0000:07:00.0: LOOP

CentOS 5, original kernel (xen and normal) and everything, Linux RAID 1. I rebooted one of my machines after doing some changes to RAID/LVM and now the two RAID partitions that I made changes to are "gone". I cannot boot into the system. On bootup it tells me that the devices md2 and md3 are busy or mounted and drops me to the repair shell. When I run fs check manually it just tells

Hi there, I have one server acting as a iscsi target running windows storage server r2 sp2 and the other server is running centos as an initiator. They are connected to a switch over a 1Gbit ethernet connection. the target is a Dell NF600 and the server running centos is a Poweredge R900. We want to move this configuration to a FC based installation using a Dell QLE2462 HBA (this is the hba we can

Thanks to the help of folks on this forum, I now have my Centos 4 box up and working, however I do have a question on how the repair actually worked. After starting the Linux Repair, the process "found my installed Linux". Some of you will remember that I had accidentally erased the /boot and /boot/grub directories, but I had most of the files saved (not the symbolic links) and

Hi, I got few servers (IBM HS20,HS21 blades, IBM xSeries 3650 & others) connected to a dual fabric san throught Qlogic HBA's (23xx, 24xx). Multipathing is done with device-mapper-multipath. On CentOS 4.x i can scan for new scsi devices without any problems, get them up with multipathing & use them without any problems. However, after i started installing CentOS 5.1 (did not

Hi all, Has anyone had any experience getting Polycom phones repaired? The screen on one of our IP600s got smashed, and I'm wondering if it's worth the effort to get it repaired, or if it'd just be cheaper to buy a new phone.

Hello folks, I have an older dovecot 2.0 (which I will migrate to a 2.2 asap, but at this point in time I need a fix). This is a dovecot 2.0 that came with Mac OS X 10.8.5 Server 2.2.5. Today, my spam/virus filtering (clamav) on the Server broke down. As a result, all my meesages got the ***UNCHECKED*** tag added to each subject. That was clearly unacceptable. SO, for the tim ebeing I have set

Hi, we are using samba 3.0.24 as a printspooler for 80 network printers with a 500kB ntprinters.tdb for some years now. When we recently restarted samba we noticed that the ntprinters.tdb automatically shrinked to 24kB and printing was no longer possible. tdbdump of the original tdb-file is impossible too: "Failed to open ntprinters.tdb" The strange thing about this: we can solve

hi, from reiserfs it`s known to happen quite often - wtmp may be corrupted; but actually I`m using only ext2/3 on the test machine. After 7 days running the RH8 system I`ve noticed the first corruption of wtmp. last shows only the line wtmp begins Wed Dec 11 09:14:52 2002 and /usr/sbin/dump-utmp wtmp spits out the history, e.g. the last line |Sun Dec 15 14:36:34 2002 ithum
