Now that I got a little time to work on my Raspberry Pi, I decided to have 2 2GB flash drives mounted at boot to save some write cycles on the SD card:<\/p>\n

After a few failed times, I googled for a while and the important bit is the 6th field in your \/etc\/fstab file. Here's mine:<\/p>\n

 <\/p>\n

[root@pi ~]# cat \/etc\/fstab
\n\t#
\n\t# \/etc\/fstab: static file system information
\n\t#
\n\t# <file system>        <dir>         <type>    <options>          <dump> <pass>
\n\tdevpts                 \/dev\/pts      devpts    defaults            0      0
\n\tshm                    \/dev\/shm      tmpfs     nodev,nosuid        0      0
\n\t\/dev\/mmcblk0p1  \/boot           vfat    defaults        0       0<\/p>\n

\t\/dev\/sda1       \/var       ext4    defaults          0       2
\n\t\/dev\/sda2       \/data      ext4    defaults          0       2
\n\t\/dev\/sda3       \/tmp       ext4    defaults          0       2
\n\t\/dev\/sdb1       \/home      ext4    defaults          0       2<\/p>\n

 <\/p>\n

The "2" in the 6th field tells the kernel to wait for the drive to be available before trying to mount it.<\/p>\n

Here's the "mount" command output:<\/p>\n

\/dev\/mmcblk0p1 on \/boot type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=cp437,iocharset=ascii,shortname=mixed,errors=remount-ro)
\n\t\/dev\/sdb1 on \/home type ext4 (rw,relatime,user_xattr,barrier=1,data=ordered)
\n\t\/dev\/sda2 on \/data type ext4 (rw,relatime,user_xattr,barrier=1,data=ordered)
\n\t\/dev\/sda3 on \/tmp type ext4 (rw,relatime,user_xattr,barrier=1,data=ordered)
\n\t\/dev\/sda1 on \/var type ext4 (rw,relatime,user_xattr,barrier=1,data=ordered)<\/p>\n
