This is what you do not get from gtar at all. So why do Linux > distros prefer gtar even though there is no Linux support? Is there any correlation between this and the warning message I see during a bootstrap like so : Warning: *** /usr/src/linux/include contains broken include files *** Warning: *** /usr/src/linux/include is not used this reason *** Warning: This may result in the inability to use recent Linux kernel interfaces Warning: *** linux/ext2_fs.h is not usable at all *** Warning: *** This makes it impossible to support Linux file flags *** You may try to compile using 'make COPTX=-DTRY_EXT2_FS' >> I doubt if they are as well maintained in linux distros as the GNU >> tool set, particularly in terms of having recent fixes backported into >> the versions carried in enterprise distros. > > gtar still did not fix bugs I reported in 1993 (e.g. the bug that > causes gtar to complain with "skipping to next header" even on it's > own archives). I am thus sure that star not not worse than gtar.... There seems to be something missing here. The subject was "schily tools" which is a lot more than star : root@rsync:/etc/default# ls /opt/schily/bin bosh cdrecord isodebug mdigest pfsh sfind star ustar bsh change isodump mkhybrid pxupgrade sformat star_sym ved btcflash compare isoinfo mkisofs readcd sgrow suntar ved-e calc copy isovfy mt sccs sh tar ved-w calltree count jsh od scgcheck smake tartest cdda2mp3 devdump label opatch scgskeleton smt termcap cdda2ogg gnutar lndir p scpio spatch translit cdda2wav hdump match pfbsh sdd spax udiff care to comment on any of these ?

Problems installing 6.2 on HP 8540w laptop
by david 07 Feb '12

07 Feb '12

Folks I've been trying to install Centos 6.2 on an HP Mobile Workstation 8540w. For various reasons, I have restarted the install many times.I use the 64-bit DVD image. The install chooses the following options a) Install with Basic Video Driver b) Skip the media scan c) Default Country, Language, Basic Storage Devices, change time zone d) Fresh Installation e) Configure network, (turn on wired Always Connect). f) Hit ALT-B to get back to examining storage devices. (I found I had to do this to get the HostName field filled in with the defaults from DHCP). [See below, frequent hangs here, in which case I power down and start again] g) If I get beyond the HostName stage, I choose the Virtual Host method and the install goes to completion successfully. The machine is connected with an ethernet cable to a LAN that is my internal NAT'ted system. The wireless button indicates disabled. I have been getting varied results with (presumably) the same starting conditions. In each case, I power off the machine, wait a few seconds, and power it on with the DVD image in place, choose "Install with basic video driver", and go through the same sequence. On many attempts, the installation sequence finishes just right, and the reboot gives me the expected root prompt. The USB mouse does not work during install, so I have to use the keyboard and touch-pad pointers. Among the anomalies I get are: 1) The first "Waiting for hardware to initialize..." is as far as it goes. Usually, it's done in a couple of seconds and goes on to a second hardware scan. Sometimes it hangs for over a minute before I give up. 2) The install appears to come to the end, the DVD is ejected, and I hit ENTER to reboot. The reboot starts and the screen goes dark. Power down and power up to boot from HD succeeds, but there was a flash of about three lines on the screen before the blue sliding bar appeared. 3) The install sequence hangs with the screen all blue except for the bottom line which reads "Running anaconda 13.21.149, the CentOS installer, Please wait ... Then after about a minute the screen blinks and goes dark. 4) The install sequence hangs on "Media Detected - Found local installation media", the CD drive idled down. 5) The install sequence hangs on "Examining Devices, Examining storage devices, with the blue slider almost at the left edge. Although this screen appears several times, the instance that hangs is the one after I've activated the wired network and hit Back. In most cases, if the system gets to the point of choosing the Virtual Host option, the installation completes successfully. So, -- is this an issue with the install procedure? Does it not treat this hardware correctly? Is there some other startup method or option I could use?

And at this point I have working VM from the tar copy, _except_ that it isn't matching a driver to the virtual NIC. I'm glad I'm not restoring a real backup with a dead machine here... Since I don't need this today, I think I'll try ReaR to see if it gets it right. It builds a bootable iso that is supposed to re-install on bare metal. -- Les Mikesell lesmikesell(a)gmail.com

new mysql installation, kinda stuck
by Bob Hoffman 07 Feb '12

07 Feb '12

I installed centos 6 as a webserver. It installed mysql. However, I guess I need mysql-server for me to use it for php and my website. I installed that. I am unable to give root a password and can go no further. I have tried mysql-secure-installation and I just get stuck at errors and no progression. I have tried mysqladmin -u root password <password> and the accompanying one that includes the hostname. ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) I am unable to use mysql with php or do anything at all with it. It was strange it installed mysql but I guess this version is different and needs more packages to work within a webserver. all attempts at using mysql without mysql-server installed just results in nothing being found (like mysqld) and the like...so I had to install the server. In 5.x I could just use mysqladmin and add roots, delete anonymous, etc. However, this time I am stuck. I uninstalled mysql-server, the perl thing that comes with it, and mysql itself, then reinstalled them, that got me no where. gotta be something I am missing here. thanks for listening.

A long time after setting up my CentOS6, I decided to create a partition in extended area for my personal data, and to automount it at boot. This is done in fstab with: /dev/sda8 /storage/data ext4 noatime,nodiratime 0 0 (see how I rely on sda, silly me!) I grabbed the UUID from `lshal` and replaced it in fstab: UUID=005374e2_5c18_437d_84d8_8069868fe54e ext4 noatime,nodiratime 0 0 .. no luck, it doesn't automount at boot. I think I'll have to investigate or get another brain update. Regards, -- wwp

distributed storage/home-made cloud recommendations
by Boris Epstein 07 Feb '12

07 Feb '12

Hello listmates, This is not specifically CentOS-related - though I will probably execute this design on CentOS if I decide to do so. It will certainly be some kind of Linux. At any rate, here's my situation. I would like to build a fairly large storage solution (let us say, 100 TB). I want this solution to be distributed and redundant. I want to be able to lose part of the machines involved and still stay operational (the bigger part, the better). I would prefer to avoid having to buy large servers to accomplish this task. What I am soliciting here is thoughts, reports from experience, recommendations, etc. Thanks in advance. Boris.

Google video chat on 5.7 using the Fedora RPM
by E Westphal 07 Feb '12

07 Feb '12

I've tried to use the Google recommended RPM to enable video chat on 5.7. Get a long list of unsatisfied dependencies. Has anyone got this to work and not created a boat full of problems? Is this something that does work in 6 and just not in 5.7 - another reason to jump in and update? Please advise. Thanks.

gtar compression achieved
by Alan McKay 07 Feb '12

07 Feb '12

Hey folks, I looked at the man page and don't see any way to do this - maybe it is a function of the compression program used I dunno. Is there any way to get gtar to report on the compression it achieved? I can't just check file sizes because I'm writing data to tape. The basic problem is that I know how much data is there to begin with but I don't know how much room it took up on the tape so I have no idea how much room is left on the tape. thanks, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"
