Ok, I had a billion (several complete system logs worth in one  
morning) of the above message in my system log of a machine used to  
host jails.  This is on a 5.3-R machine. The file system mentioned, / 
local/jail/jail1  is a /dev/md -- md(4) type file system used to  
constrain the user in that specific jail to a certain amount of space  
and to make it easy to dump that filesystem for backups.


I don't know what the user of that jail was doing or when it started  
happening.  Is the inumber 166876 an inode inside the filesystem?   
Or what does it refer to?


I don't know why it continuously stuck that message thousands of  
times in the system log but I killed the process with that PID and  
all was well.


My interesting issue is that on ssh login to OTHER JAILS on other / 
dev/md type filesystems, that had nothing to do with that jail or  
filesystem, login was prevented as the login process would print a  
similar message  to the one above in the login window over and over  
and over and would never complete login.


/local/jails/jail1: write failed, filesystem is full

/local/jails/jail1: write failed, filesystem is full

/local/jails/jail1: write failed, filesystem is full

/local/jails/jail1: write failed, filesystem is full

/local/jails/jail1: write failed, filesystem is full

Only when I killed the offending process did it allow the login to  
continue.  However, this seemed to be hit or miss.  Sometimes an ssh  
login to a jail (not the offending jail) would work and sometimes it  
would do the above.  Why would this issue with this one jail file  
system affect jails that had nothing to do with the full filesystem  
and what  happens at login that would dump these console type  
messages to the ssh login window?


Thanks
Chad

It is an inode number of the filesystem that has been mounted to 
/local/jails/jail1. Inodes in a filesystem are uniqe, but each 
filesystem holds its own inode numbers that have nothing to do with 
inode numbers of an other filesystem.

That sounds weird. Have you checked the output of 'df -ih' at the host? 
I like to see it.

yes, the word inumber was strange; instead of inode or inode number  
-- hence the question.

Yes.  I have fixed the issue so the currrent results are not the same  
as they were but they are close


/dev/md22501.6G 
1.5G 11M99%7828   2276903%   /local/jails/jail1


Before it was like 1.6G1.6G-704k  100%  with very similar  
inode results


thanks!!
best regards
