[zfs-discuss] partioned cache devices
Hi all, I'm having some trouble with adding cache drives to a zpool, anyone got any ideas? muslimwookie@Pyzee:~$ sudo zpool add aggr0 cache c25t10d1p2 Password: cannot open '/dev/dsk/c25t10d1p2': I/O error muslimwookie@Pyzee:~$ I have two SSDs in the system, I've created an 8gb partition on each drive for use as a mirrored write cache. I also have the remainder of the drive partitioned for use as the read only cache. However, when attempting to add it I get the error above. Here's a zpool status: pool: aggr0 state: DEGRADED status: One or more devices is currently being resilvered.

Unfortunately no, neither guest NTP, ntpdate or rdate in crontabs, nor VirtualBox timesync settings, alone or even combined for test (though known to conflict) - nothing has definitely helped so far. We also have some setups on rather not-loaded hardware where after a few days of uptime the clock stalls to the point that it has a groundhog day - rotating over the same 2-3 second range for hours, until the VM is powered off and booted. Conversely, we also have dozens of VMs (and a few hosts) where no such problems occur. Weird stuff... //Jim ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

I was thinking of SmartOS, but the site mentions Intel support for VT, but nothing for AMD... The Opterons dont have VT, so i wont be using XEN, but the Zones may be useful... OpenIndiana or OmniOS seem like the most likely candidates. You can run VirtualBox on OpenIndiana and it should be able to work without VT extensions. Also note that without the extensions VirtualBox has some quirks. Most notably, lack of "acceleration" and support for virtual SMP. But unlike some other virtualizers, it should work (does work for us on a Thumper also with pre-VTx Opteron CPUs). However, recently the VM "virtual hardware" clocks became way slow. I am at loss so far, the forum was moderately helpful - probably the load on the host and induced latencies have their role. But the problem does happen on more modern hardware too, so VTx (lack of) shouldn't be our reason... //Jim ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

We use XEN/PV on X4200 for many years without problems. dom0: X4200+openindiana+xvm guests(PV): openindiana,linux/fedora,linux/debian (vmlinuz-2.6.32.28-xenU-32,vmlinuz-2.6.18-xenU64) regards Heiko ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
