Hello gentoo forum,
Like in subject, fstab can't find my usb device, and mount it.
BUT, if I restart openRC init, everything is fine. Fstab can find it, and mount.
It is very annoying to restart openRC and log in. There must be another way.

Code:

# BLKID OF USB SAMSUNG
#/dev/sda1: LABEL="Gentoo" UUID="9ace0ae7-2c82-401b-a078-8b725fa38bd4" BLOCK_SIZE="512" TYPE="xfs" PARTUUID="5e2ef541-03b4-43b1-b52a-6515fc44b34e"

# ROOT PARTITION
PARTUUID=988508bb-d3b2-4057-af4b-3db1bcde3e5d / xfs defaults 1 1

#PENDRIVE USB SAMSUNG
PARTUUID=5e2ef541-03b4-43b1-b52a-6515fc44b34e  /home/anon xfs defaults 0 1


Any suggestion? I can provide more information, just ask me.

It looks to me as if the drive isn't in a settled state by the time you try to mount it. It can take a long time between the kernel loading the driver and probing the bus, and the drive being ready -- it could be seconds for magnetic disks. But even if it's only milliseconds, it could be too long.

I don't know if there's a nice solution to this problem using OpenRC. In the past I've just mounted the disk using an init script with a time delay before the mount. It's not very elegant. I, too, would like to know if there's a nicer way.

BR, Lars.

Thanks. Init script has resolved the mount problem.

Template for anyone:
Code:


  GNU nano 8.0                                                /etc/init.d/mount_pendrive                                                         
#!/sbin/openrc-run

depend() {
    after localmount
}

start() {
    ebegin "Mounting pendrive as /home/anon"
   
    # Replace these variables with your actual values
    PARTUUID="FILL IT"
    MOUNTPOINT="also this"
    FILESYSTEM="and this"

    # Attempt to mount the partition
    mount -t $FILESYSTEM PARTUUID=$PARTUUID $MOUNTPOINT
   
    if [ $? -eq 0 ]; then
        eend 0 "Pendrive mounted successfully"
    else
        eend 1 "Failed to mount pendrive"
    fi
}

stop() {
    ebegin "Unmounting pendrive from /home/anon"
    umount /home/anon
    eend $?
}
