SATA error
by Fajar Priyanto 28 Mar '06

28 Mar '06

Hi all, Finally I temporarily migrate my mailserver to another box. It has been experiencing troubles with the SATA discs (Maxtor and Western Digital). I then upgraded the kernel to the latest one: 2.6.9-34.ELsmp and now smartd can run. When I do: smartcl -d ata -a /dev/sda, it says some errors but I don't know what does it mean. This is the result: http://pastebin.com/624613 The problems it encoutered were: time out on device. Pls take a look at the pastebin for details. Is the drive still ok? Running smartcl on sdb gives no error. Thanks, -- Fajar Priyanto | Reg'd Linux User #327841 | Linux tutorial http://linux2.arinet.org 15:15:23 up 6:20, 2.6.15-1.1830_FC4 GNU/Linux Let's use OpenOffice. http://www.openoffice.org

Is the SRPM for kernel-2.6.9-34.106.unsupported available?
by Dave Hatton 28 Mar '06

28 Mar '06

Hi, I can't see the SRPM for kernel-2.6.9-34.106.unsupported in the centosplus repo. Is it just kernel-2.6.9-34.EL.src.rpm with an modified .config or were any additional patches added? Thanks Daveh

kernel source
by Andrew Zahn 28 Mar '06

28 Mar '06

Hi, I am trying to install the kernel src rpm that I've downloaded from the CentOS ftp, kernel-2.6.9-22.EL.src.rpm. I hope to compile the kernel with XFS enabled. However, I have tried to simply run: [root@se4 ~]# rpm -iv kernel-2.6.9-22.EL.src.rpm and it complains back: warning: group builder does not exist - using root warning: user builder does not exist - using root warning: group builder does not exist - using root warning: user builder does not exist - using root warning: group builder does not exist - using root warning: user builder does not exist - using root .... then an rpm -q kernel-2.6.9-22.EL.src.rpm says: package kernel-2.6.9-22.EL.src.rpm is not installed Anyone know what is going on?? ps. I have tried to install the CentOSplus kernel with xfs and that is completely unstable for me. thanks, Andrew

Extremely slow disk transfers with SATA disks
by Vanja Hrustic 28 Mar '06

28 Mar '06

I have installed CentOS 4.2, recently, on new computer. Everything seemed to work fine. However, we've found out that disk transfers are incredibly slow, and I just can't figure out what to do in order to fix it. Computer is now running CentOS 4.3 (updated it 1 hour ago), and same thing is still present. I hoped kernel upgrade might fix it, but it didn't. Computer has 2 SATA disks, 200GB (Maxtor 6Y200M0) and 80GB (Maxtor 6L080M0). There are no errors or any other indications of problems in logs/dmesg. Copying 500MB file takes around 210 seconds. Around 2.3MB/sec. Doesn't matter if I am copying from one hard disk to another, or onto the same hard disk. When copying, vmstat shows: r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 160 525928 1060 278044 0 0 1609 1112 1387 1146 9 4 39 47 0 0 160 525928 1060 278044 0 0 0 0 1084 745 0 0 100 0 0 0 160 525844 1060 278044 0 0 0 0 1067 795 2 0 98 0 0 0 160 525844 1060 278044 0 0 0 0 1084 745 1 0 99 0 0 0 160 525844 1072 278044 0 0 0 156 1073 757 0 0 100 0 0 1 160 525564 1148 278228 0 0 240 0 1129 1136 2 1 77 20 0 1 160 522708 1176 281256 0 0 1600 0 1283 1155 0 2 0 98 0 1 160 519380 1184 284568 0 0 1672 0 1327 1231 0 2 0 98 3 1 160 516404 1196 287368 0 0 1412 0 1264 1126 1 1 0 98 0 1 160 513524 1196 290424 0 0 1536 0 1353 1926 11 2 0 87 0 3 160 510132 1208 293544 0 0 1544 7348 1407 2163 24 6 0 71 0 1 160 513780 1216 289972 0 0 1412 140 1360 1536 9 3 0 88 2 0 160 515316 1220 288464 0 0 1104 0 1341 2067 47 4 0 49 0 1 160 518996 1216 284608 0 0 1712 0 1333 1676 34 7 0 59 0 1 160 516820 1224 286832 0 0 2052 0 1318 2025 25 4 0 71 1 2 160 512388 1228 291024 0 0 2952 8736 1433 1431 6 4 0 90 2 1 160 504772 1244 295304 0 0 3076 76 1382 1453 15 5 0 80 0 1 160 502340 1252 301096 0 0 3332 0 1358 1624 7 5 0 88 0 1 160 495236 1260 308216 0 0 3588 0 1323 1631 2 3 0 95 1 1 160 487620 1268 315640 0 0 3716 0 1355 1175 7 2 0 91 0 2 160 480708 1276 322120 0 0 3204 16732 1423 1354 2 5 0 93 You can see text version here (in case this got wrapped): http://www.vanja.com/vmstat.txt I've tried vmstat on my machine, with IDE disks, and I've noticed that I ave much less 'cs' (context switches), although it might be because I'm not having as many processes in the background (problematic computer is running KDE :). On my computer, number of blocks in (bi) gets into tens of thousands, while problematic computer has 1500-3000 bs/second. Does anyone know what I might do in order to find what the problem might be? I couldn't find any SATA specific tools, which might help with troubleshooting. hdparm -tT tests show: /dev/sda: Timing cached reads: 2408 MB in 2.00 seconds = 1202.98 MB/sec Timing buffered disk reads: 150 MB in 3.02 seconds = 49.61 MB/sec /dev/sdb: Timing cached reads: 2628 MB in 2.00 seconds = 1313.54 MB/sec Timing buffered disk reads: 166 MB in 3.02 seconds = 54.88 MB/sec All filesystems are ext3. This "problematic" computer has nforce3 motherboard, I have nforce2. Same CentOS, but no SATA on my computer. This really affects complete performance of computer, and any help or ideas are welcome. Btw, no problems with transfer under Windows :( Thanks. Vanja

Odd installation hang.
by Lamar Owen 27 Mar '06

27 Mar '06

For the archives: I had an odd installation hang on an older Athlon MB; KT133 I believe. SuSE 10.0 and Fedora Core 5 installers ran fine; CentOS 4.2 and 4.3 hung with the last line on the screen referencing running /sbin/loader (or is that /sbin/installer....don't typically see it enough to remember); the cursor froze at that point. SuSE 10.0 successfully installed on this box. After trying all the normal tricks, like turning ACPI off, using the BIOS IRQ table, etc, I noticed that the FC5 installer mentioned something about disabling IRQ6. IRQ6?!? That's the floppy controller; but there's no floppy drive configured or cabled. Hmmm.... no place in the BIOS to disable the floppy controller ?!? Ok, let's tell it it has a 3.5 1.44MB floppy (even though it doesn't!), and not to stop on floppy errors. Lo and behold, that fixed the hang. Something in the CentOS 4 installer that runs right after /sbin/loader was hanging, unless it had a floppy out there, even when there was no floppy out there. But, and I repeat, SuSE 10.0 installed flawlessly, and the FC5 installer came up fine. But the CentOS 4 installer did not until I told the BIOS to lie about having a floppy. -- Lamar Owen Director of Information Technology Pisgah Astronomical Research Institute 1 PARI Drive Rosman, NC 28772 (828)862-5554 www.pari.edu

Shells
by Scott Silva 27 Mar '06

27 Mar '06

This is giving me some grief, and I couldn't get anything decent from Google. What shell is the best to allow things like vacation to work, but not allow logins. It seems that /bin/false used to work in RedHat 9, but not in Centos 4. -- MailScanner is like deodorant... You hope everybody uses it, and you notice quickly if they don't!!!!

Sun quad fast ethernet: Failed to allocate mem resource
by Louis Lagendijk 27 Mar '06

27 Mar '06

Hello all, I have this nice Sun quad fast ethernet card that I would like to use in my Centos server. I have used it in the past on my old server without problems. When I insert it in my new server (Epox 8k3a AMD mobo, XP1800 processor) I get the following messages in dmesg: ACPI: PCI interrupt 0000:02:00.1[B] -> GSI 5 (level, low) -> IRQ 5 sunhme.c:v2.02 24/Aug/2003 David S.

I have been googling around, but have not been able to find a solution. Does anybody hee have an idea what the problem migt be, or how to tackle the problem? for the record: I am running the 2.6.9-34.EL kernel, but had the problem with older kernels as well. As the card worked under Centos 4 on my Asus K7M mobo, it looks as a mobo or bios problem, but I am not sure. Any help is very much appreciated. kind regards, Louis -- Louis Lagendijk <louis(a)lagendijk.xs4all.nl>

Sendmail vulnerability
by Peter Farrow 27 Mar '06

27 Mar '06

Dear All, I noticed that sendmail rpms were updated by yum a day or so ago, however, how can I check if the versions installed are patched for the recently exposed exploit.... I guess that since I am running sendmail-8.13.1-3 (which appears to be the latest according to yum) and the articles describe 8.13.6 as having the fix that I may be vulnerable.... P.
