problems with CentOS chroot
by Maxim Soldatov 17 Dec '07

17 Dec '07

Hello, I've got strange problem with centos (as well as rhel btw) chrooted environment. First of all I created simple directory with only the libs for 'bash' and 'id' tools: ---- # chroot testcase/ bash-3.1# id uid=0 gid=0 groups=0,1,2,3,4,6,10 ---- Yes, I even do not have /etc/ directory inside testcase/ , but id shows groups from the _host_ root account. I tried to create full chroot with all the libs and tools based on debian testing, but the same result: # id uid=0 gid=0 groups=0,1,2,3,4,6,10 but if I do # ls /etc/shadow /etc/passwd /etc/group /etc/group /etc/passwd /etc/shadow then # id uid=0(root) gid=0(root) groups=0(root),1(daemon),2(bin),3(sys),4(adm),6(disk),10(uucp) Args, quite strange for me. I tried to use strace to identify where is the problem, and only one thing I found is 530 error on read() : [cut] open("/etc/group", O_RDONLY|0x80000) = -530 getgroups32(0, NULL) = 7 getgroups32(7, [0, 1, 2, 3, 4, 6, 10]) = 7 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 write(1, "uid=0 gid=0 groups=0,1,2,3,4,6,1"..., 34) = 34 [cut] 530 is EIOCBRETRY according to errno.h, but, honestly, I do not know what does it mean and what I can do with it. SElinux - disabled via /etc/selinux/config. CentOS release 4.4 (Final) с ядром 2.6.9-67.ELsmp. as well as Red Hat Enterprise Linux Server release 5.1 (Tikanga) 2.6.18-53.1.4.el5 Could anyone please explain what is going on and what have I done wrong? Thanks a lot for your time and sorry for my english. -- Maxim Soldatov

Re: [CentOS] Expandable network storage

No it probably would not provide the performance unless run on 10 Gbe. Of course that depends on the number of write transactions, 1Gbe maxs around 100MB/s, so if you need faster performance look elsewhere. I doubt it's reliability too, nbd is a simple protocol, but as such doesn't provide for error recovery. Best bet, build performance storage with redundancy on 1 server, then if budget allows duplicate it on another and use something like drbd to replicate it (synchronous if network speed allows, asynchronous otherwise) for high availability. -Ross -----Original Message----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS mailing list <centos(a)centos.org> Sent: Mon Dec 17 04:56:57 2007 Subject: RE: [CentOS] Expandable network storage Hi all, I'm currently thinking about similar configurations, and (also for cost reasons :-) am also thinking about GNBD with two standard servers as a "poor man" redundant storage - but I'm wondering if that gives enough performance for running databases (in my case Oracle) on top of it. The configuration I'm thinking about would be two current Dell servers with hardware RAID 10 and connected by a dedicated 1 GBit crossover-cable, running both the cluster software and Oracle.

I kind of just sat back and watched it develop. I learned a lot from it all. I have been reading all of the documentation on clustering provided by Centos/Red Hat, and find I travel in circles. I read one chapter and answer a self-imposed question but I end up asking myself another. What I really want to do is have HA for any service I run (which is mostly HTTP, MySQL, FTP, and the common things like that). I want to run that to redundant storage somewhere that is real easy to expand by just adding more hardware (server or disk drive). I started exploring this by using the Cluster Suite as a base and then looked into each aspect of the cluster and invariably got stuck on the storage side of this. I see how I can maybe set this up originally, but the expansion just doesn't seem to be there. I don't really want to go the route of Fibre channels and ISCSI, and would prefer to use common hardware (which sort of suggests GNBD). If anyone cares to offer suggestions, with a pretty clear explanation trail (thanks Ken Price for your link to a step-by-step), I would really like to see it, as I'm not getting anywhere with the documentation. I hope to get some hardware to play with shortly, and maybe that'll make things clearer. I'm sure it one of those deals where once I get it done, it'll be so obvious. I just need a little kickstart to help me get there.

Qlogic HBA scanning issues with CentOS 5.1 ?
by Finnur Örn Guðmundsson 17 Dec '07

17 Dec '07

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 notice this problem with CentOS 5) i cannot seem to rescan without huge problems. Sometimes when i rescan after presenting a new LUN to the server nothing is detected, and sometimes the device comes in without any problems at all. Sometimes i even loose some paths after rescanning.....again, i had no problems at all with CentOS 4.x. I use the Qlogic script (Dynamic Target and LUN Discovery <http://support.qlogic.com/support/EULATemplate/Template.aspx?TemplateID=9&p…> 2.2) to scan for new luns. Has anyone had any issues with scanning for new devices off san after upgrading to 5.1 ? Thanks, Finnur

It is available on all CentOS.org mirrors and via bittorrent, see this link to download ISOs: http://isoredirect.centos.org/centos/4.6/isos/ This release corresponds to the upstream vendor U6 release. Also released in the updates repository for CentOS-4.6 are all updates through December 15th, 2007. The work for the i386 and x86_64 ServerCDs is in progress. If you are currently using another version CentOS-4 version, using this command will upgrade you to CentOS-4.6: yum update -------------------------------------------------------------------- Major changes for this version are: * samba has been updated to version 3.0.25b. This addresses several critical issues affecting interoperability with Windows 2003™ and Windows Vista™ (resolved in recent upstream releases). * autofs5 is included in this release as a Technology Preview. This new version of autofs resolves several long-standing interoperability issues in multi-vendor environments. * There is a technology preview of OpenOffice-2.0 included in the updates directory. You can install this OOo2 preview alongside the current OOo-1.1.5 version, or you may install the OOo2 preview alone. We apologize that this was not included on the ISOs, however it was not on the upstream ISOs and we followed that layout. To List the new OpenOffice-2.0 RPMS with yum use this command: yum search openoffice.org2 | grep i386 | grep -v langpack For finding Language Packs (if you want other than English) do: yum search openoffice.org2 | grep langpack Use "yum install <pkg_name1> <pkg_name2>" to install the packages that you want, or "yum info <pkg_name1> <pkg_name2>" to obtain more information about them. * A new yum included in CentOS-4.6 requires the installation of yum-metadata-parser. The yum-metadata-parser package contains a metadata parser for yum written in C. It speeds up the metadata parsing phase of yum considerably and does not change yum behavior in any other way.

After 5.1 update $releasever is still 5
by Robert Moskowitz 16 Dec '07

16 Dec '07

I have performed the 5.1 update via the 5 repo on a couple of systems. I then went to switch these systems to my new local repo using ther $releasever variable. It still has the value of 5, not 5.1 Where is this set? Why was it not changed to 5.1? On the one clean install from the 5.1 isos, $releasever is at 5.1 I think.
