I/O error moving mailbox [Problem Solved]

Hello to the list!,


finally I could solve the problem thank to another list user (Wesley) 
that sent me a private message.

He suggested me to trace using "strace" the imapd process while I was 
trying to move the mailbox.

When I did that I discovered that the problem could be related with the 
quota file:

/var/lib/imap/quota/c/user.col1901 exists but It was empty


pcocol01:~ # cat /var/lib/imap/quota/c/user.col1901
pcocol01:~ #


Not like other mailbox quotas:

pcocol01:~ # cat /var/lib/imap/quota/c/user.col5000
430654051
10000000
pcocol01:~ #

When I tried to set the quota for that user I received the same error:


localhost> lq user.col1901
localhost> sq user.col1901 10000000
quota:10000000
setquota: System I/O error

After "stracing" while I was trying to set the quota I got the same 
problems so I decided to remove the empty file 
(/var/lib/imap/quota/c/user.col1901) as Wesley suggested me.

After removing the file the problem looked like solved:

pcocol01:~ # cyradm -u cyrus -pass XXXXXXXXXX localhost
localhost> sq user.col1901 10000000
quota:10000000
localhost> lq user.col1901
  STORAGE 0/10000000 (0%)
localhost> renm user.col1901 user.col1901 part3
localhost>


Thank you very much to all of you!
