I currently use a raspberry-pi that I connect over with SSH, since it`s physical location is >100km far away. After running 1.5 years, it has now some I/O-errors when writing into the database. In the syslog, I found the following entries:
Jan 28 12:24:33 raspberrypi kernel: [ 1573.144567] print_req_error: I/O error, dev mmcblk0, sector 12371948
Jan 28 12:24:41 raspberrypi kernel: [ 1581.336573] print_req_error: I/O error, dev mmcblk0, sector 12371949
Jan 28 12:24:49 raspberrypi kernel: [ 1589.528572] print_req_error: I/O error, dev mmcblk0, sector 12371950
These entries are also listed in dmesg
.
The command df -l
gives:
Filesystem 1GB-blocks Used Available Use% Mounted on
/dev/root 32GB 6GB 25GB 18% /
devtmpfs 2GB 0GB 2GB 0% /dev
tmpfs 3GB 0GB 3GB 0% /dev/shm
tmpfs 3GB 1GB 3GB 1% /run
tmpfs 1GB 1GB 1GB 1% /run/lock
tmpfs 3GB 0GB 3GB 0% /sys/fs/cgroup
/dev/mmcblk0p1 1GB 1GB 1GB 21% /boot
tmpfs 1GB 0GB 1GB 0% /run/user/1001
So I guess, that mmcblk0p1
is my SD-card. However when listing dev
, I can see the following devices:mmcblk0 mmcblk0p1 mmcblk0p2
So:
- Is my SD-card really bricked? How can I doublecheck that?
- What exactly is
mmblk0
,mmcblk0p1
andmmcblk0p2
?
