Hi,
I recently install BackupPC3 on a server where BackupPC2 was previously
running. I didn't update from the previous version, but instead choose to
delete all elements relative to previous install and do a fresh install. I'm
familiar with BackupPC install.
BPC is installed on a FC3, and the backup folders are located to a nas
server (a Pegasus 250Gb NAS), mounted thru NFS on /mnt/nas.
Now the problem:
- When I leave BackupPC running automatically, backups seems to work.
- I can use the web interface, and setup BackupPC & my server parameters
- When I go to "my server" summary page, NFS mount hangs.There's no
information on backup PC web admin interface. I just can't list anymore my
/mnt/nas directory & backup PC can't access NAS. Instead there is an I/O
error in the directory listing (ls /mnt/nas).
- On /var/log/messages or backuppc logs, there's no information about the
problem.
- If I unmount / and remount /mnt/nas, directory listing come back.
- If I go again to the Backup PC web interface, NFS mount hangs again
Notes:
- Only few pages of the web interface hangs NFS mount. The summary
page (
http://localhost/cgi-bin/backuppc/BackupPC_Admin?host=myserver.mydomain)
make NFS hang each time.
- If I remount the NFS volume just after summary page display, I can
lauch a complete backup manually using the "Force complete backup" button (
http://localhost/cgi-bin/backuppc/BackupPC_Admin?host=myserver.mydomain&hostIP=myserver.mydomain&doit=1&action=Start_Full_Backup
)
- I tried to play with nfs mount options. Initially, there where an
rsize/wsize optim :
nas:/shares/Volume1/nas /mnt/nas nfs rw,addr=
192.168.254.254,rsize=8192,wsize=8192,timeo=14,intr 0 0
- I tried to leave defauts (1K blocks) without sucess. Same things
happens.
nas:/shares/Volume1/nas /mnt/nas nfs rw,addr=
192.168.254.254,timeo=14,intr 0 0
I don't know where to look at since ther's no informations in logs about the
hang cause. Does anybody have got any idea of what happens?
