I have this problem: my screen seems not wide enough in R. My true computer monitor is very wide, so I wish that I can line up the text when I stretch it wide. i.e.: This is typical R returns: > summary(a) V1 V2 V3 V4 F:625 Min. :20020103 EMC : 34 Min. : 9300300 L:944 1st Qu.:20020530 BRW : 27 1st Qu.: 9323865

so I've had a drbd replica running for a while of a 16TB raid thats used as a backuppc repository. when I have rebooted the backuppc server, the replica doesn't seem to auto-restart til I do it manually, and the backupc /data file system on this 16TB LUN doesn't seem to automount, either. I've rebooted this thing a few times in the 18 months or so its been running... not

I have a SPA-2001 and I didn't realize I could use calling features on an analog handset. Does that mean you can dial *77 and use a VOIP feature? (like forward or hold)?

I am running a two-node web cluster on OCFS2 via DRBD Primary/Primary (v8.3.8) and Pacemaker. Everything seems to be working great, except during testing of hard-boot scenarios. Whenever I hard-boot one of the nodes, the other node is successfully fenced and marked ?Outdated? * <resource minor="0" cs="WFConnection" ro1="Primary" ro2="Unknown"

Hiya, I'm new to Centos but learning rapidly but I have been using FreeBSD. I'm trying to setup a HA NFS server using 2 machines. Both machines are running 4.3 updated to the latest via Yum. I did yum groupinstall drbd-heartbeat and yum install kernel-module-drbd-kernel-module-drbd-2.6.9-34.EL to match my kernel. The problem I have is that on 1 machine drbd works fine, but when I start

Hello, Sorry to sound like a bad record, but I'm trying to figure out why I'm getting "Bad gzip magic numbers" errors when ISOlinux is trying to inflate the kernel. Right now I'm clueless as to what's wrong. I've tried various kernels compiled on a few different platforms. Has anyone ever seen this before? ANyone know where a better forum to ask this question

Hi all. I have two hosts with drbd: kmod-drbd83-8.3.8-1.el5.centos drbd83-8.3.8-1.el5.centos and kernel (CentOS 5.7): 2.6.18-308.4.1.el5 After a recent upgrade of kernel I have had two sitiuations when my ext3 filesystem on /dev/drbd0 became read-only. I've checked disks with smartctl -t long, they are ok. There are no messages with disks problems in /var/log/messages | dmesg. I've made

I began an update of one of our servers via yum and, coincidentally or not, I have been getting the following logged into the message file since: messages:Jan 7 15:55:51 inet07 kernel: post_create: setxattr failed, rc=28 (dev=dm-0 ino=280175) Now, this tells me that dev dm-0 is out of space but, what is dm-0? So, can anyone tell me what is happening and why? -- *** E-Mail is

So I'm working with the iSCSI Initiator and an EqualLogic SAN. I'm not sure when this might have happened, but it appears that the /dev/sdc device is missing, yet the /dev/sdc1 partition exists AND is mountable. Is there a method to re-create the /dev/sdc device? I cannot dd or fdisk it, obviously, but I can mount the /dev/sdc1 partition and it works just fine. Not having the /dev/sdc

Hi Dumb question i think but how can i make devices permissions persist after a reboot. I dont think i have come across this issue before but i have some SAN disks that need to be oracle:dba as their perms but after a reboot they reset back to brw------- 1 root root 120, 49 Nov 30 10:40 /dev/emcpowerd1 any thoughts? thanks
