Re: [DNG] Boot hangs with usb disk active in fstab
FYI, I had a similar problem booting from a USB drive on an old Debian machine a long time ago. May have been Wheezy, or ever Sarge. The problem in my case was that the kernel was taking a while to settle the USB module, so at the early boot stage, it "knew" it was supposed to mount the USB drive, but it did not yet know the USB drive. If I remember correctly, I had to build a custom initrd with a script that simply forced the load of USB, then waited until it was able to detect the USB drive in question. Sorry, it was a long time ago, and I did not write it up as I try to do now. But, I vaguely remember inserting a script that simply insmod'd the module(s), then went into a loop which only exited after a certain amount of time, or if the USB drive was detected. Then, I just let the regular boot process to continue. Again, relying on memory, it seems the USB drivers take a finite amount of time to settle and actually be ready to work, and that time is variable depending on the device and the system. May be a total wild goose chase, but the problem you're having sounds similar. NOTE: it slowed my boot time significantly, but since it was a server, an additional 15 seconds did not matter so long as it came up. I THINK I was trying to do a RAID-1 for / from the USB drives, but that may have been a different time.

As I've read the thread, the delay is between querying the USB bus for devices and trying to read from them. In your case, the device is been seen on the bus, but the mount fails - one possible cause of that is that the USB bridge device and/or disk are not ready in time, i.e. that the chippery and/or disk between them are not read to read data within 5s (if that's the default) of the devices being enumerated. So changing this parameter is to see if giving a longer time between enumerating the devices on the bus (at which point, the chippery and disk should initialise and spin up) and actually trying to read form the disk. If it does, great; if it doesn't then there's a different problem. > A smaller disk is no option, since this is my media server at home. It is > filled with 66%. I think the idea was simply to try a smaller disk and see if that works. It's all in an effort to narrow down the list of possible causes - e.g. if it still won't mount then it being a big disk isn't the problem; if it does mount then at least you know it's not the USB chippery in the drive case. At present, there are a lot of possible causes, which makes fixing the problem tricky. Simon ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

Hi,
you could try to stick at various boot stages a little program like this:
__
#include
#include
#include
#include
#include
int main(int argc, char ** argv)
{
/* Eventually adjust the args to your liking */
if (mount("/dev/sda1", "/hdd", "ext4", 0, NULL) == -1) {
fprintf(stderr, "%s: %s\n", "mymount", strerror(errno));
syslog(LOG_ERR, "%s", strerror(errno));
} else {
fprintf(stderr, "%s: %s\n", "mymount", strerror(errno));
syslog(LOG_INFO, "%s", strerror(errno));
}
return 0;
}
__
Compile with:
gcc -Wall mymount.c -o mymount
This will log error or success to syslog with some hopefully meaningful
messages:
Jun 14 17:03:13 devuan kernel: EXT4-fs (sdm1): mounted filesystem with ordered
data mode. Opts: (null)
Jun 14 17:03:13 devuan mymount: mymount: Success
Hope this helps.
Ciao,
Tito

When you mount it interactively the path is different and maybe it's
waiting for some input.
Try to add to the script:
PATH=${PATH}:/sbin:/usr/sbin
and
mount /dev/disk/ /mnt/mountpoint http://contact.xaq.nl/

I mounted a disk created ext4 with a newer Debian on a machine running an older Debian and it would not mount (at all). I looked it up in a script I made and for me it was the metadata_csum option that was inserted by the newer Debian and the old one did not support this.

Even though the disk was powered on its own, it didn't start spinning before the driver started it. I solved it by adding a delay to the kernel before mounting the rootfs - there was a parameter for that. Maybe it's just enough to add such a delay before trying to mount your USB disk.

Hi, I'm running Devuan Beowulf on an Odroid C2 mini computer. Since it's internal flash disk is limited, I run it with an external usb drive attached. When this disk is active in /etc/fstab the boot process hangs forever. I can ping it, so networking is started, but I cannot login, because sshd is not running. Since this is a headless system, I cannot see boot messages to find out where it hangs. I cannot attach a monitor because I have no suitable cable. Any ideas how to debug this problem? This is the fstab entry: LABEL=Elements /hdd ext4 defaults 0 2 Booting with this entry commented out works fine, and I can mount the disk as normal after boot. But this way many daemons are missing its data and have to be restarted after mount. Jochen ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
