Title: Problem with Dar2 backup
Post by: Paperguides on June 17, 2011, 01:08:48 PM

I am trying to implement a replacement backup system as I unconvinced that I can rely on Iomega's REV drive any longer (or Iomega ever again!)

My solution is to use DAR2 with a set of USB Hard disks attached to a workstation; one for every day.

I set it up and the first backup worked OK.  Subsequent attempts fail with the error:

/bin/mkdir: cannot create directory `/mnt/dar2/hd_backup': File exists

Attempts delete the directory with Winscp and/or putty fail.

[root@thurley ~]# cd /mnt/dar2
[root@thurley dar2]# ls
daily  hd_backup  manual  usbdisk
[root@thurley dar2]# rm hd_backup
rm: cannot lstat `hd_backup': Input/output error
[root@thurley dar2]#

The server is running SME 7.5.1

Can anyone help?

try this both ways

1.
rm ./hd_backup

2.
go to any other place and do
rm /mnt/dar2/hd_backup

 :(

A web search on "cannot lstat" suggest a corrupt inode and running fsck.  Can I do this on a live system?

You may be able to do fsck on a live system, but it is not a good idea.

Send your users a nice email, suggest they take a coffee break, and shut the system down for the 15-30 minutes required.
