Hi All, I had a slice with zfs file system which I want to mirror, I followed the procedure mentioned in the amin guide I am getting this error. Can you tell me what I did wrong? root # zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT export 254G 230K 254G 0% ONLINE - root # echo |format Searching for disks...done

I''m using zfs not to have access to a fail-safe backed up system, but to easily manage my file system. I would like to be able to, as I buy new harddrives, just to be able to replace the old ones. I''m very environmentally concious, so I don''t want to leave old drives in there to consume power as they''ve already been replaced by larger ones. However, ZFS

This hook script tries to address the fact that a RHEV-H installation will format all the storage devices available in the machine in order to create HostVG and AppVG with all the available space. It may be the case that RHEV-H needs to respect and co-exist with a proposed partitioning scheme, not getting all the storage space for HostVG and AppVG volume groups. The proposed solution adds the

Hi, I am doing working on enabling Transcendent Memory(OLS '09) support on lguest. For the same, I need ballooning support for lguest. Is there an implmentation of Virtio Balloon driver, that I can use for my purpose? Could someone give me an insight, as to how to go about, for implementing this myself, incase I dont find this patch... Thankyou. -- Gaurav Kukreja +91 997 030 1257
