Author Topic: udevd timeout killing modprobe - Sans connected to dell r710 running tinycore  (Read 500 times)

no idea what's going on; but... basically, i'm trying to get my software working on tinycore, i used to run it on ubuntu, but i like how relatively easy it is to make custom tinycore images and pxe boot them.

just erasing hdds... that may or may not be good; thus the need to connect 100 so hdds to one server sort of thing. i want to eventually get away from having so many connected to one server, as the hardware glitches are horrific... but for now i need something inbetween to help transition. 

were running on dell r710 servers, with lsi hba's connected to... various san arrays.

basically...
when the server is loaded; 0 hard drives show up, and then i load the scsi extension, and get this error showing up for a while... after a few minutes hard drives start to populate and then the error eventually stops showing... and this takes forever. :(

i dont see anything obvious to me in dmesg... well, a lot of the hdds connected are probably bad...


the [###] stuff in the screenshot is just a timer form my software.

oops. ss didnt attach.

basically, takes forever for hdds to populate, bad/broken hdds are typically mixed in... and this error spams.

also, i dont need the os or whatever to load the partition tables of the hdds in the SANs. maybe that would help reduce bugs / decrease the time to attach things? havent the slightest idea if that would be possible / where to look.

Hi HotNoob
Based on the screenshot, I think it's having problems finding/loading a driver.

The devices in question are:
Device 1000:0060    Subsystem 1028 1f0c    PERC 6/i Integrated RAID Controller
https://pci-ids.ucw.cz/read/PC/1000/0060
https://wiki.debian.org/LinuxRaidForAdmins#megaraid_sas
and
Device 1000:0072    Subsystem 1000 3080    9200-8e [LSI SAS 6Gb/s SAS/SATA PCIe x8 External HBA]
https://pci-ids.ucw.cz/read/PC/1000/0072
https://wiki.debian.org/LinuxRaidForAdmins#mpt2sas
I believe  mpt2sas  was replaced with  mpt3sas  on more recent kernels.

Did you install the  scsi-KERNEL.tcz  extension?

Hi HotNoob
If the problem persists with  scsi-KERNEL.tcz  installed, you may need
to copy the drivers to the initrd:
I'm getting the  Internal Forum Error  message again. See the attached
file for directions. Replace  core.gz  with  corepure64.gz  if running 64 bit.

The  megaraid_sas.ko.gz  and  mpt3sas.ko.gz  drivers both accept
parameters. Run  modinfo  on them to see what they are.

hmmmn...
might have loaded a bit faster; not sure. still getting the same udevd errors / behaviour.

i see in modinfo mpt3sas, that it has an alias: mpt2sas
would that maybe explain the mpt2sas in dmesg instead of mpt3sas?

Hi HotNoob
Based on the modinfo result you posted I presume you added the drivers to the initrd.
If all of your devices are SAS 2, you can add this boot code to to your bootloader:
Code: [Select]
mpt3sas.hbas_to_enumerate=1
... i see in modinfo mpt3sas, that it has an alias: mpt2sas
would that maybe explain the mpt2sas in dmesg instead of mpt3sas? ...
I don't know for sure, but I don't think so. The alias for your device is:
Code: [Select]
alias:          pci:v00001000d00000072sv*sd*bc*sc*i*
