Can you say what the default kernel policies related to file system flushing are these days? My knowledge may be outdated. Personally I don't care that much whether _my_ docs are saved immediatelly or not, I am connected to a 99.something % reliable power grid, and a loss of a byte once in a blue moon isn't the end of the world I guess. I believe in using menu options like "Safely remove storage" - they imply that without it I may be in trouble. I don't know Windows in detail but I know they do file buffering too. So since leaving single task OSes as CP/M or MS/DOS behind I don't expect that "written by app" means "written to disk". The servers have UPS and battery-backed controllers to ensure this. Of course I am in trouble if the file system gets itself in the knot while flushing - one reason to avoid file systems with a bad reputation. Most of the time kernel developers are writing better and safer code than application developers. vi and emacs are a bit of the exception that proves the rule. Regards Peter

mail storage in a distributed database
by Russell Coker 10 Apr '12

10 Apr '12

Does anyone know of a mail store that uses a distributed database like Cassandra? I want something that has a delivery agent with a similar interface to maildrop or procmail and which has POP and IMAP servers to provide client access. IBM had a research project implementing a mail server on Cassandra but as far as I can tell they released nothing other than a PDF. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

iscsi (was RE: drdb and mdadm and more)

Wheezy has lio target now which is marketed as faster and better than everything else, although there are arguments about that from the other iscsi target camps... I think lio also has an initiator but I haven't seen Debian packages for that yet. I'm using lio after using iscsitarget (iet) without any problems. James

USB3 kernel support
by James Harper 09 Apr '12

09 Apr '12

In the interests of getting around 1TB of data onto disk faster for offsite backups, we bought a PCIe USB3 adapter: lspci 16:00.0 USB controller: NEC Corporation uPD720200 USB 3.0 Host Controller (rev ff) pspci -n 16:00.0 0c03: 1033:0194 (rev ff) and also a USB3 caddy that holds bare disks. This was working great on a test machine so we moved it across to a production machine and it's being nothing but trouble. The test machine is a HP ML110G6, and the production machine is a HP ML370G5. The adapter uses the xhci_hcd module, and after it plays up and I try and unload and load the module it says: [353709.836103] xen: registering gsi 19 triggering 0 polarity 1 [353709.836113] xen_map_pirq_gsi: returning irq 19 for gsi 19 [353709.836117] xen: --> pirq=19 -> irq=19 (gsi=19) [353709.836121] Already setup the GSI :19 [353709.836125] xhci_hcd 0000:16:00.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19 [353709.836204] xhci_hcd 0000:16:00.0: xHCI Host Controller [353709.836225] xhci_hcd 0000:16:00.0: new USB bus registered, assigned bus number 1 [353709.836253] xhci_hcd 0000:16:00.0: can't setup [353709.836349] xhci_hcd 0000:16:00.0: USB bus 1 deregistered [353709.836419] xhci_hcd 0000:16:00.0: PCI INT A disabled [353709.836423] xhci_hcd 0000:16:00.0: init 0000:16:00.0 fail, -19 So something has gotten stuck somewhere. I'm running debian 3.2.0-2-amd64 kernel. It seems that the USB3 caddy is no longer working as it also exhibits similar symptoms when plugged in to a USB2 port, but I've tried other USB2 and USB3 devices on the USB3 adapter and they appear to be doing similar things so now I'm not so sure. Any suggestions? Can anyone name an adapter that is working well for them? Thanks James

linux label printer?
by Craig Sanders 08 Apr '12

08 Apr '12

can anyone recommend a decent reasonably-priced small label printer that works well with linux and standard text-processing tools. powered from the USB interface would be nice but not essential. multiple suppliers of consumables would also be nice but, i guess, unlikey. i want to print some labels to put on stuff. like disk identifiers to stick on the handles of my hot-swap bays. nothing fancy, just needs to do a simple job, do it well, and not cost too much per label. if anyone has any tricks for controlling them from the command line (rather than openoffice or some gui label-printing app), i'd love to hear about it. e.g. in the first instance, I want to print sticky lables based on the output of: $ /bin/ls /dev/disk/by-id/| sed -rne '/ata-(ST|WDC)/s/ata-.*_//p' | grep -v -- -part 6VP3FWAG 9VP16X03 9VP18CCV 9VP4P4LN 9VP4RPXK 9VP509T5 WD-WCASJ2114122 WD-WCASJ2195141 WD-WMAV50817803 WD-WMAV50933036 i also want to be able to print once-off labels with something as simple as 'echo text | lpr -Plabelprinter' craig -- craig sanders <cas(a)taz.net.au> BOFH excuse #256: You need to install an RTFM interface.

Hardware to give way
by Sebastian 08 Apr '12

08 Apr '12

Hi, I have some hardware to give away. 1. ASUS A7V8X-X mainboard with a AMD Athlon processor. 256 MB RAM. Zalman fan on the CPU. Gigabyte GeForce2 MX 400 video card (dual display support). Sound Blaster sound card. DVD drive. Floppy drive. No power supply. All in a black Antec case. I haven't power this up for a while and don't have a ready way to test it; however, I believe it to be in working order. 2. Pentium 4 Socket 478 with Pentium 4 processor. 256 MB RAM. 3. Belkin Wireless G Desktop Network Card Hardware can be picked up from Northcote or maybe the city. E-mail me if you're interested in any or all of the above. Cheers, Sebastian

luv lists
by Lindsay Sprinter 07 Apr '12

07 Apr '12

Sorry to be a pain in the neck right to the end but my internet access system died over night and I am unable to remove myself from all of the lists including luv-announce would some one with the required access please do that for me as its is likely to be week before I can build a new box. The old ones only 14 years old with a 4 year old version of Debian on it so it is likely it has died of old age. lindsay
