Was using emonSD-17Jun2015 on my emonPi 2.5 with low-write 8.5 emoncms.
Created a backup using the backup utility. No issues.
Compressed backup file is 10.1 Mb. Uncompressed, around 211 MB.
Updated my SD card by writing the emonSD-03May16.img
Ran update using setup > administration. All is current.
Attempted to restore the backup file.
Web interface fails saying “Cannot write: No space left on device”
Tried running the manual method, same result.
SD Card is 4 GB.
Am I going to be forced to upgrade to an 8 GB card in order to import my data? (cuz that sucks)
Is there something I can purge in the file system to make room for the process?
log into your emonPi via SSH. Then type in:
df -h
and you should get something like this:
pi@emonpi:~ $ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/root 3.4G 1.8G 1.5G 55% /
devtmpfs 483M 0 483M 0% /dev
tmpfs 487M 0 487M 0% /dev/shm

/dev/sda1 59G 40G 16G 72% /mnt/usb
pi@emonpi:~ $
then copy your results into a post.
EDIT: And then let’s look at the data directory:
ls -al /home/pi/data{/,/import,/uploads}
Filesystem Size Used Avail Capacity iused ifree %iused Mounted on
/dev/disk0s2 232Gi 67Gi 165Gi 29% 17514403 43325339 29% /
devfs 196Ki 196Ki 0Bi 100% 678 0 100% /dev
map -hosts 0Bi 0Bi 0Bi 100% 0 0 100% /net
map auto_home 0Bi 0Bi 0Bi 100% 0 0 100% /home
and with: ls -al /home/pi/data{/,/import,/uploads}
I get:
ls: /home/pi/data/: No such file or directory
ls: /home/pi/data/import: No such file or directory
ls: /home/pi/data/uploads: No such file or directory
I’m sorry, I’m not a good Linux guy, so thanks much for the help.
Edit - fixed formatting. Moderator, BT
This looks like a report of a Unix (Mac?) drive (/dev/disk0s2 = disk 0 slice 2)
The above looks like your own computer and we need to access your emonPi. Open the Terminal again and then follow this section to log on to your emonPi via SSH:
Well that’s embarrassing… here you go:

That’s probably a little more like what you wanted to see 
Yes, I’m afraid the data you are trying to restore is too big to fit on the default data partition on the 4GB SD card. You will need to upgrade to an 8GB SD card then run $ emonSDexpand to expand the data partition to fill the remainder of the 8GB card. This will create plenty of space for logging data for many years to come 
.
Got it! I’ll make the hour long trip to town today and get one.
Incidentally, nice work on the new emoncms interface. From what I can see so far it’s a great improvement. Now to see if I can export to csv with the missing data points included… I’m so hoping that works now as I have a hell of a time aligning data in spreadsheets when 10 out of 12000 records are out of alignment.
Thanks for the assistance, folks! I sure appreciate all you geeks
