I'm no raid expert, so perhaps someone can help. :)

raid0 situation, with 2 drives. Roughly 80gigs free and it says out of
space:

sycamore# df
Filesystem  1K-blocks     Used    Avail Capacity  Mounted on
/dev/raid0c 116402501 31915120 78667255    28%    /incoming

and inodes as:
Filesystem  1K-blocks     Used    Avail Capacity iused   ifree  %iused 
Mounted on
/dev/raid0c 116402501 31915120 78667255    28%    2283 29243155     0%  
/incoming

Now if I ssue something like:

sycamore# cp /netbsd /incoming
/incoming: write failed, file system is full
cp: /incoming/netbsd: No space left on device

If I clear 2 megs space, I get 2 megs to play with before it is full.

I notice an inconsistency here, is this the cause of the problem? What
needs to be done to correct it? Will we lose raid?


Also found that I can create a file, like:

sycamore# dd if=/dev/zero of=testing bs=1024

/incoming: write failed, file system is full
dd: testing: No space left on device
42825+0 records in
42824+0 records out
43851776 bytes transferred in 45 secs (974483 bytes/sec)

-rw-r--r--   1 root  wheel  43851776 Feb  6 11:54 testing


Leaving the file there, I can then go create a second file:

sycamore# dd if=/dev/zero of=testing2 bs=1024

/incoming: write failed, file system is full
dd: testing2: No space left on device
42769+0 records in
42768+0 records out
43794432 bytes transferred in 38 secs (1152485 bytes/sec)

-rw-r--r--   1 root  wheel  43851776 Feb  6 11:54 testing
-rw-r--r--   1 root  wheel  43794432 Feb  6 11:55 testing2

and slowly fill up the system?



Any reply would be appreciated!
