hello all,
i hope my message is clear:
when ufsdump start, nfs clients have "NFS server scr not responding
still trying"
------- ------ ----- ------
| D1000 |---| E250 |--- Ethernet 100 Mb/s -- | U10 |--| LTO2 |
------- ------ ----- ------
every night, ufsdump start to save a complete partition /export/home
/export/home is on D1000 configured with SDS RAID 0+1 (200GB useful on
400GB total)
It takes 8 hours to dump 120 GB.
I'm using ufsdump because i think it's the better tool to dump an active
filesystem
When i detached a submirror, it tooks 9 hours to reconstruct the
mirror, so it's not a solution for daily backups.
Do you think that ufsdump is the cause of problem?
I wonder what will be the best solution, but as this server is in prod,
i cannot do more tests:
- sol1: plug LTO2 directly on E250, anybody knows if it will solve the
"NFS server scr not responding still trying" problem?
- sol2: don't use ufsdump. fssnap?
- sol3: trying ufsdump from U10, on nfs mounted partition?
thanks in advance,
gerard
