Mail Merge data to a pdf file by overlaying the data on the image
by Gregory P. Ennis 07 Jun '15

07 Jun '15

Everyone, I am looking for a utility that I can use to do a mail merge of data to a pdf image file. The image file does not have any active fields, but will be just an image file. I would like to overlay names addresses etc. We currently do this with a pcl file by just overlaying the data with pcl print positions. However, in order to get the pcl file from an original pdf file we have to use gimp to convert the pdf to pcl file, and we always lose a little resolution. I was wondering if anyone knows of a utility to perform this function without first converting the image to a pcl file. Thanks, -- Greg Ennis

heavy IO load when working with sparse files (centos 6.4)
by Ron E 31 Mar '15

31 Mar '15

Dear List, We have noticed a variety of reproducible conditions working with sparse files on multiple servers under load with CentOS 6.4. The short story is that processes that read / write sparse files with large "holes" can generate an IO storm. Oddly, this only happens with holes and not with the sections of the files that contain data. We have seen extremely high IO load for example copying a 40 or 80gb sparse file that only has a few gigs of data in it. Attempts to lower the io priority and cpu priority of these processes do not make any measurable difference. (ionice, nice) This has been observed with processes such as: cp rsync sha1sum The server does have to be under some load to reproduce the necessary conditions. The cases we have seen involve servers running 10-30 guests under kvm. Load is in acceptable norms when the processes are run, such as load avg 5-15 on a 24 core (12 core with HT enabled) server. We also verify before starting such a process that the spindle with the file we're working on is not being unduly hammered by another process. These servers have one hardware raid controller each (Dell H700 controller with write cache enabled) and multiple raid arrays (separate sets of physical spindles). Interestingly, the IO storm is not limited to the array / spindles where the sparse file resides but affects all IO on that server. We have looked extensively and not found any account of a similar issue. We have seen this on configurations that are 'plain vanilla' enough to think that this is not something specific to our environment. Wondering if anyone else has seen this and if any suggestions on gathering more data / troubleshooting. We wonder if we've found either a raid controller driver issue, an OS issue or some other such thing. What seems to point in this direction is that even with ionice -c3 which should prevent the process from using IO unless the storage is idle, an io storm which appears to saturate the entire raid bus on a given server can occur. Thanks in advance.

Centos 6.4 on Xserve, IPMI error
by Arno B 31 Mar '15

31 Mar '15

Hello! I'm trying to install Centos 6.4 64 bit on this Xserve: http://www.everymac.com/systems/apple/xserve/specs/xserve-intel-xeon-2.8-ei… I got a bootloader from: http://blog.christophersmart.com/2009/07/23/linux-on-an-apple-xserve-efi-on… as none of the official Centos releases (full, minimal, network 64 bit) boot on this machine. They all crash when loading the bootx64.conf. I have built a USB stick with a working bootx64.efi, grub.cfg, together with an initrd and a vmlinuz from the isolinux folder. These seem to get me into booting a kernel until something called IPMI is starting to throw errors at me: Console: switching to colour frame buffer device 128x48 fb0: VESA VGA frame buffer device ipmi message handler version 39.2 IPMI System Interface driver. ipmi_si 0000:09:00.4: enable device (0002 -> 0003) ipmi_si 0000:09:00.4: PCI INT C -> GSI 16 (level, low) -> IRQ 16 ipmi_si: Adding PCI-specified kcs state machine ipmi_si 0000:09:00.7: enable device (0000 -> 0003) ipmi_si 0000:09:00.7: PCI INT D -> GSI 17 (level, low) -> IRQ 17 ipmi_si: Adding PCI-specified bt state machine ipmi_si: Trying PCI-specified kcs state machine at mem address 0x90841000, slave address 0x0 irq 16 IRQ 16/ipmi_si: IRQF_DISABLED is not guaranteed on shared IRQs Using irq 16 ipmi: Found new BMC (man_id: 0x00003f, prod_id: 0x0003, dev_id: 0x20) IPMI kcs interface initialized ipmi_si: Trying PCI-specified kcs state machine at mem address 0x90840000, slave address 0x0 irq 17 Refined TSC clocksource calibration: 2792.999 MHz.

*very* ugly mdadm issue
by m.roth＠5-cent.us 06 Sep '14

06 Sep '14

We have a machine that's a distro mirror - a *lot* of data, not just CentOS. We had the data on /dev/sdc. I added another drive, /dev/sdd, and created that as /dev/md4, with --missing, made an ext4 filesystem on it, and rsync'd everything from /dev/sdc. Note that we did this on *raw*, unpartitioned drives (not my idea). I then umounted /dev/sdc, and mounted /dev/md4, and it looked fine; I added /dev/sdc to /dev/md4, and it started rebuilding. Then I was told to reboot it, right after the rebuild started. I don't know if that was the problem. At any rate, it came back up... and /dev/sdc is on as /dev/md127, and no /dev/md4, nothing in /etc/mdadm.conf, and, oh, yes, mdadm -A /dev/md4 /dev/sdd mdadm: Cannot assemble mbr metadata on /dev/sdd mdadm: /dev/sdd has no superblock - assembly aborted Oh, and mdadm -E /dev/sdd /dev/sdd: MBR Magic : aa55 Partition[0] : 4294967295 sectors at 1 (type ee) ee? A quick google says that indicates a legacy MBR, followed by an EFI.... I *REALLY* don't want to loose all that data. Any ideas? mark

mairadb doesn't prompt for user/pass
by Tim Dunphy 02 Sep '14

02 Sep '14

Hello, I discovered today that CentOS 7 has replaced MySQL with MariaDB. Which is fine, it's seems really similar. And I was already aware that it was written by the original team that wrote mysql. It's cool that the mysql command still gets you in! This is the version I have: [root@web1:~] #mysql --version mysql Ver 15.1 Distrib 5.5.37-MariaDB, for Linux (x86_64) using readline 5.1 But for some reason all I have to do is type the word 'mysql' to get me into the database. That's ok for initial setup I guess. But once I was in a did away with all the accounts that either had blank set for the username, and updated all the accounts to use passwords. MariaDB [mysql]> select User,'@',Host,Password from user; +-------+---+-----------+-------------------------------------------+ | User | @ | Host | Password | +-------+---+-----------+-------------------------------------------+ | root | @ | localhost | *8328225AE4A663FAKEFAKEFAKEFAKEFAKE93D61 | | root | @ | web1 | *8328225AE4A663FAKEFAKEFAKEFAKEFAKE93D61 | | root | @ | 127.0.0.1 | *8328225AE4A663FAKEFAKEFAKEFAKEFAKE93D61 | | admin | @ | localhost | *8328225AE4A663FAKEFAKEFAKEFAKEFAKE93D61 | +-------+---+-----------+-------------------------------------------+ 4 rows in set (0.00 sec) I also did a search from root to find any my.cnf files and didn't find any that has user accounts in them. Also I find that for the root accounts I can't seem to login even if I set the password in the database without encryption and copy/paste the password into the prompt. However the non-root account (admin) does let you in with the password. So I'm wondering how to secure mariadb so that it doesnt' let you in without typing in a username and password and also why it doesn't let you log in as 'root'? Is the root account disallowed from logging in by default? Thanks Tim -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B

why does centos 7 want to install mariadb instead of mysql ?

Install Centos 6 x86_64 on Dell PowerEdge 2970 and a SSD (hardware probing issues)
by Jason Pyeron 01 Sep '14

01 Sep '14

I have a fleet of 2970s and we are upgrading the hardrives on the motherboard SATA ports (A/B not the PERC backplane) when a "detecting hardware" is performed the system crashes, reboots and gives an E1422 error code (useless video: https://www.youtube.com/watch?v=PhyMeUHJar4). We narrowed it down to a motherboard BIOS issue, if we remove the SSD or add noprobe to the kernel the installer does not crash. But when specifing "noprobe" it does not appear to have the loopback driver (and likely many more). ERROR: failed to mount loopback device /dev/loop0 on /mnt/runtime as /tmp/install.img: (null) INFO: mounting stage2 failed Next steps, I already lost my vacation to this, I hope to keep my sanity: Load drivers from kernel boot line? Blacklist drivers on the kernel boot line? Serial cable logging of boot? Other? -Jason -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- - - - Jason Pyeron PD Inc. http://www.pdinc.us - - Principal Consultant 10 West 24th Street #100 - - +1 (443) 269-1555 x333 Baltimore, Maryland 21218 - - - -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- This message is copyright PD Inc, subject to license 20080407P00.
