first, what is the version ??
you can get with : onstat -
1) check the file '/Ifmxdata/dbspace1_3'.
if is a link, this link is valid???
if is linked to :
- a raw device, this raw is accessible??
to check a raw device you can use dd command to read all data...
- a coocked file (file of OS like any other ) , try copy to another location and remake the link.
2) to try put this chunk online use the onspaces :
onspaces -s <dbspacename> -p /Ifmxdata/dbspace1_3 -o <offset> -O
No, the link was not mirrored. However, I figured that since the offline chunk contained system catalogue info and I had a backup which was restored on my test server about a month or two back and there were no changes to the actual tables recently, I then ftp'ed the chunk from test into the production box, overwriting the existing chunk which was offline. Then I refreshed my link and was able to get it back online with onspaces.
