Greetings again,
I've been continuing to fool with this. I'm hoping someone smarter
can shed a little more light on it. Here's what I've discovered since my last post.....
It seems that on my system, it takes more than the allowed 10 seconds for the disks to appear. I removed "quiet" from my boot command line and it timed out looking for UUID=xxxx..... . So I looked for it and it definitely was not there. None of the sdXx devices were. I looked again, and yet again (ls /dev/sd*) and after about the 3rd or 4th attempt they showed up. So then, I mounted /dev/sdc3 to /new_root/, typed 'exit' and after a warning about possibly failing to run as a user instance, it booted.
Any clues as to why this occurs? I'm trying to find a way to increase
Well, I was trying the same thing but via GRUB_PRELOAD_MODULES (which didn't work) so gave this a go. Still didn't work. First I just added just "megaraid_sas" which failed to solve it, so then I added a bunch. Just about everything "(MODULES=(megaraid_sas xfs scsi_mod libcrc32c ahci xhci_pci ohci_pci ehci_pci xhci_hcd ohci_hcd ehci_hcd sr_mod sd_mod libata shpchp i2c_piix4 sp5100_tco k10temp fam15h_power nouveau nvidia_drm nvidia) )" but it still takes nearly 30 seconds for the sdX devices to appear with blk-mq enabled. Strange. Thanks for your thoughts though. I'm not done banging on it yet. Kind regards On Fri, May 11, 2018 at 5:38 AM LoneVVolf <lonewolf@xs4all.nl> wrote: than I the
pre-boot disk probe timer if possible. So far, all I've found are tips about speeding up the boot process, not slowing it down.
Many thanks in advance.
In order for your drives to be detected the kernel modules needed by the hardware must be loaded and active. Your description matches a situation where some needed module is loaded too late in the boot process.
Use lspci -k to determine which kernel modules are needed for your sata / raid controllers and add that one to the modules= line in mkinitcpio.conf . Incase it's unclear which module is needed, try the one that handles the boot parameter (scsi_mod) .
