I?ve posted this on the forums at https://www.centos.org/forums/viewtopic.php?f=47&t=57926&p=244614#p244614 - posting to the list in the hopes of getting more eyeballs on it.

I''m using LVM to create CoW disk on my Xen box. The problem is that the VMs are not able to access the LVM devices after running for some hours. I have the folowing LVM configurations (result of a lvscan): ACTIVE Original ''/dev/xen-vg/RH-EL.WS.4'' [4.00 GB] inherit ACTIVE Snapshot ''/dev/xen-vg/RH-EL.WS.4-01'' [200.00 MB] inherit ACTIVE

I have an smbd process that is using alot of cpu on HP-UX 11.11 using Samba 2.2.3a. It looks like the application on the client side is trying to open and close a ton of files, many of which do not exist. When I do a trace on the smbd process, I see repeated calls to lstat64 to what looks like all of the device files on my unix server. Here is a little bit of the trace. It goes through all of the

I have searched the list, and don't see this covered or didn't search for the right words. I'm running CentOS 4.8 and have some DVD's for 5.4. I have a lot of customized and additional software installed and would like to avoid starting over with a scratch install. After the upgrade from the DVD I would do a yum upgrade to 5.5. Is this a workable (and safe) thing to do? What

Solaris 10 5/08 Customer migrated to a new emc array with a snap shot and did a send and receive. He is now trying to set quotas on the zfs file system and getting the following error.

Hi, One of our servers has a too small root partition on LVM and needs to be resized. Can / be safely increased online, without a reboot?

I'm replacing an ancient Solaris 'ipf' firewall/router with a brand new CentOS 6.3 system. In the olden days, I successfully used the attached iptables script (as /etc/rc.local) on Red Hat 5.x systems, but this doesn't seem to be quite working on the new system. Specifically, while it seems to be routing ok, you cannot connect to anything on the inside net (e.g., with ssh or

Hi all I accidentally deleted a LVM volume directly (rm /dev/System/newcpanel) and now my LVM's are all messed up. I have a snapshot from one of the other LVM's, as follows lvcreate -s -n newcpanel /dev/System/wiseguy -L10G But, instead of running lvremove /dev/System/newcpanel I ran rm /dev/System/newcpanel ( I don't know why) So, now I have waisted space on my server, and I

I created a 1TB RAID1. So far it is just for testing, no important data on there. After a reboot, I tried to mount it again # mount /dev/mapper/vg00-btrfsvol0_0 /mnt/btrfs0 mount: wrong fs type, bad option, bad superblock on /dev/mapper/vg00-btrfsvol0_0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or

Dear list, I want the 1st, 2nd, 5th, and 6th columns of mtcars. After copying them, the columns become numeric class rather than data frame. But, when I copy rows, they data frame retains its class. Why is this? I don't see why copying rows vs columns is so different. > class(mtcars) [1] "data.frame" > head(mtcars) mpg cyl disp hp drat wt qsec vs

Not a centos specific question here, but if anyone can save me from shooting myself in the foot would appreciate any pointers.... I have an older centos 4.7 box that I recently replaced with a newer one running centos 5.3. I'd like to add the hard disk from the older one to the newer one before I scrap it for good. I don't care about the data on it, would just like the extra drive

First let me say that I'm not a sysadmin, but am simply wearing that hat this week so please excuse my ignorance. I need to temporarily move some virtual servers from a CentOS-KVM platform to a CentOS-XEN platform while I do some upgrades to the CentOS box. I've created a local LV, and used DD and SCP to transfer the block device from the VKM machine to the XEN machine. For quite a

I did some additional testing - I stopped Kafka on the host, and kicked off a disk check, and it ran at the expected speed overnight. I started kafka this morning, and the raid check's speed immediately dropped down to ~2000K/Sec. I then enabled the write-back cache on the drives (hdparm -W1 /dev/sd*). The raid check is now running between 100000K/Sec and 200000K/Sec, and has been for several
