We have several auto-sync jobs from a Nexenta system to this system. I have now disabled these jobs. I just wonder where logs etc. I can find any information on what is going on on the system when it fails.<o:p></o:p> <o:p> </o:p> The symtoms are always the same. The vmware nfsshare disappear. So I just reshare them (nfs set nfsshare=…. /hgst4u60/vmware-ds-1. Then the root ZFS folders of all local drives that I think have snapshots enabled are unmounted. So I have to unmount them all hard and remount them. Also the root ZFS folders from replicated ZFS folders are unmounted. This is why I assume that there is a link between the problems and auto-sync or snapshotting.<o:p></o:p> <o:p> </o:p> <img border="0" src="cid:Logo_Telespazio_180_px_signature_eng_b58fa623-e26d-4116-9230-766adacfe55e1111111111111.png"> Oliver Weinmann Senior Unix VMWare, Storage Engineer Telespazio VEGA Deutschland GmbH Europaplatz 5 - 64293 Darmstadt - Germany Ph: + 49 (0)6151 8257 744 | Fax: +49 (0)6151 8257 799 <a href="mailto:oliver.weinmann@telespazio-vega.de">oliver.weinmann@telespazio-vega.de</a> <a href="http://www.telespazio-vega.de">http://www.telespazio-vega.de</a> Registered office/Sitz: Darmstadt, Register court/Registergericht: Darmstadt, HRB 89231; Managing Director/Geschäftsführer: Sigmar Keller From: Lawrence Giam [mailto:paladinemishakal@gmail.com] Sent: Freitag, 23.
