similar to: LVM recovery after pvcreate

[This email is either empty or too large to be displayed at this time]

OK folks, I'm back at it again. Instead of taking my J4400 ( 24 x 1T disks) and making a big RAID60 out of it which Linux cannot make a filesystem on, I'm created 4 x RAID6 which each are 3.64T I then do : sfdisk /dev/sd{b,c,d,e} <<EOF ,,8e EOF to make a big LVM partition on each one. But then when I do : pvcreate /dev/sd{b,c,d,e}1 and then pvdisplay It shows each one as

Hi all, I am looking for a tool which let me monitor memory consumption per process on CentOS 5/6. The tool should be able to save its history so I could see what amount of memory was consumed yesterday/week ago/etc by each process. Can you recommend anything like that ? Best regards P.

Hi all. I'm using libvirt 1.2.6 I want to use lvm storage for my virtual machines. But i want to use new lvm2 feature - thin pool. How can i do that in libvirt?

Hello, we are using hardware array and its vendor recommends the following setting in /etc/system: set sd:sd_max_throttle = <value> or set ssd:ssd_max_throttle = <value> Is it possible to monitor *somehow* whether the variable becomes sort of bottleneck ? Or how its value influences io traffic ? Regards przemol

Hello, one of our developers is developing his Web applications (PHP-based+MySql) on 64-bit Fedora. He would like to use the same, 64-bit environment on CentOS. I am not against 64-bits (we use it for many, many years using Solaris) but what concerns me is the stability of 64-bit Linux. Can you share your experience regarding stability of 32-bit and 64-bit CentOS ? Does anybody use 64-bit CentOS

Hello, I am trying to migrate one of our fedora-based servers to CentOS. Our PHP developers doesn't allow us to switch because there are no crucial (for them) php packages: php-smarty php-adodb php-accelerator It is not acceptable for us to download sources and compile them and repeat the process each time there is a security bug. Can you recommend any repository which will deliver all the

Hello, can I use chroot users in their home directories under centos 5.* using standard packages ? How about chrooted sftp in centos 5.* ? If I cannot - do I have to use centos 6.* ?

Hello, we are using several centos servers under Vmware. We are having more and more requests for server space for each business application (let assume that these business requests are for different type of services: databases, web apps, application servers etc. I wonder which solution is better: 1. new CentOS under vmware (having several CentOS servers under Vmware) or 2. new CentOS under KVM

Hello, we have one application which gets some data from our database but to print just one result it connects many times to the database over WAN. Of course there are some performance related problems with this type of work. I'd like to analyze (not necessary online) its tcp flow especially its latency (using port redirect on switch). Do you know any software (similar to tcpdump or so) which

Hi, we have CentOS ftp server (vsftpd) which has a lot of users who are writing and reading a lot of small files from/into its own accounts (and other servers - using samba client - are reading these files and putting them into outside database). Since this server is under heavy load its availability is important. >From time to time we "crash" this server (don't ask why ...) but

Hi, I have still problem with samba and AD. And I still know nothing :( Sometimes it works OK, but seldom. Generaly it can't get users from AD. System boots and wbinfo says that there is no users or that there is only 10 users (in AD I have about 1100). I think that this is problem with timeout, because sometimes it works OK. Sometimes linux reboot helps... And simetimes my dhcp on

All, I understand that ZFS gives you more error correction when using two LUNS from a SAN. But, does it provide you with less features than UFS does on one LUN from a SAN (i.e is it less stable). Thanks, Shawn This message posted from opensolaris.org

Hello, we have installed non-repository based software on our centos servers (e.g. vmware tools). Each time we do 'yum update' we have to run several scripts to check if these software works after update. Sometimes we forget ... It it possible to configure any sort of triggers which will run automatically after 'yum update' ? I'd like to avoid writing shell wrappers for yum

Hello, we have several physical servers (CentOS 5.*) with rather critical applications where (because of stability) we don't do regularly 'yum update'. In virtualized environemnts (under Vmware) we do a snapshot, then 'yum update', reboot and if something is wrong we rollback the snapshot. On physical servers we cannot do that. I have read about rollback option of rpm but not

this has never happened to me before, and I'm somewhat at a loss. got a email from the cron thing... /etc/cron.weekly/99-raid-check: WARNING: mismatch_cnt is not 0 on /dev/md10 WARNING: mismatch_cnt is not 0 on /dev/md11 ok, md10 and md11 are each raid1's made from 2 x 72GB scsi drives, on a dell 2850 or something dual single-core 3ghz server. these two md's are in
