This seems similar: EXT4 "No space left on device (28)" incorrect but there is no explanation

I created an ext4 filesystem on a RAID 1 array with:

mke2fs -t ext4 -T small /dev/md0

tune2fs -l >> http://pastebin.com/P5eKXmgC

tried this too:

mke2fs -t ext4 -b 1024 /dev/md0

tune2fs -l >> http://pastebin.com/ujLtE95L

Copying a single directory with many tiny files I get:

cp: cannot create regular file `/mnt/storage_temp/pics/pic3412.jpg': No space left on device

space used 5%

inodes used 1%

I manually tried:

cp /source/test1.jpg /mnt/storage_temp/pics/test1.jpg --- error
cp /source/test1.jpg /mnt/storage_temp/pics/test2.jpg --- ERROR
cp /source/test1.jpg /mnt/storage_temp/pics/test3.jpg --- no error

Notes: RAID 1 disks are error free. I tried mv instead of cp and got the same thing. I tried omitting -T small with no effect

Can somebody help me understand this magic?

  • please let me know what's unclear, i'll try to improve it. it's irrelevant where else i might have posted this question. what matters is that this might be the only place with the answer if you can actually help. – user1434058 Jun 06 '12 at 01:33
  • Please provide the output of `sudo tune2fs -l /dev/md0`. – mgorven Jun 06 '12 at 04:35
  • idea is to have "block_size = 1024", otherwise tiny files waste space, both of these game me the same error around the 10GB mark: mke2fs -t ext4 -T small http://pastebin.com/P5eKXmgC mke2fs -b 1024 http://pastebin.com/ujLtE95L – user1434058 Jun 06 '12 at 12:44

How small is that partition? According to man mke2fs, the -T small gets automatically used if the partition size is between 3 - 512 megabytes. Is the partition that small? If not, do you really need that mke2fs option?
