[zfs-discuss] Any recommendations on Perc H700 controller on Dell Rx10 ?
Hi folks: At work, I have an R510, and R610 and an R710 - all with the H700 PERC controller. Based on experiments, it seems like there is no way to bypass the PERC controller - it seems like one can only access the individual disks if they are set up in RAID0 each. This brings me to ask some questions: a. Is it fine (in terms of an intelligent controller coming in the way of ZFS) to have the PERC controllers present each drive as RAID0 drives ? b. Would there be any errors in terms of PERC doing things that ZFS is not aware of and this causing any issues later ? -- Sriram ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] Ideas for ghetto file server data reliability?
To add: Even if you have great faith in ZFS, a backup helps in dealing with the unknown. Consider: - multiple disk failures that you are somehow unable to respond to. - hardware failures (power supplies, motherboard, RAM). - damage to the building. - having to recreate everything elsewhere - even another system - for a special reason. ECC RAM will help ensure that the data given to ZFS is error free. ZFS will ensure that it's able to detect errors while writing to the storage medium. There are still issues such as disks reporting that data has been written, but not having written it yet. Could someone elaborate a bit more on this aspect, please? -- Sriram On 11/16/10, Edward Ned Harvey wrote: >> From: zfs-discuss-boun...@opensolaris.org [mailto:zfs-discuss- >> boun...@opensolaris.org] On Behalf Of Toby Thain >> >> The corruption will at least be detected by a scrub, even in cases where > it >> cannot be repaired. > > Not necessarily.

You cannot non-destructively repartition. If you have any data on that disk, move it off (to the other disks, for e.g.), reinstall into a smaller partition, and then get that data back. -- Sriram ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

My only tip for Linux based iSCSI clients would be that you should use CentOS 5.2 based dm (device multi path) for connecting to iSCSI using multipath. One of the dm developers at Netapp recently gave a talk at a LUG meet we hosted at our office, and he explained how Netapp and Redhat put in a lot of effort to ensure that dm on Redhat is stable. After some experiments at work, I have concluded that dm on CentOS 5.2 is much more stable than on any other Linux distro. > > -- Sriram > ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Is this a good idea? I share a three disk pool over NFS for some VMWare ESXi based hosting. There is considerably high disk I/O caused by the apps that run on these VMs. ZFS + NFS is working fine for me. I intend to experiment with iSCSI later when I free up some machines for such an experiment. -- Sriram ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

>From the presentation "ZFS - The last word in filesystems", Page 22 "In a multi-disk pool, ZFS survives any non-consecutive disk failures" Questions: If I have a 3 disk RAIDZ with disks A, B and C, then: - if disk b fails, then will I be able to continue to read data if disks A and C are still available ? If I have a 4 disk RAIDZ with disks A, B, C, and D, then: - if disks a and b fail, then I won't be able to read from the mirror any more.
