[zfs-discuss] SUNWsmbs SUNWsmbskr for Sparc OSOL snv_134?

2011-12-18 Thread andy thomas
Does anyone know where I can still find the SUNWsmbs and SUNWsmbskr packages for the Sparc version of OpenSolaris? I wanted to experiment with ZFS/CIFS on my Sparc server but the ZFS share command fails with: zfs set sharesmb=on tank1/windows cannot share 'tank1/windows': smb

Dear List, I have a storage server running OpenIndiana with a number of storage pools on it. All the pools' disks come off the same controller, and all pools are backed by SSD-based l2arc and ZIL. Performance is excellent on all pools but one, and I am struggling greatly to figure out what is

I know some others may already have pointed this out - but I can't see it and not say something... Do you realise that losing a single disk in that pool could pretty much render the whole thing busted? At least for me - the rate at which _I_ seem to lose disks, it would be worth

I'd look at iostat -En. It will give you a good breakdown of disks that have seen errors. I've also spotted failing disks just by watching an iostat -nxz and looking for the one who's spending more %busy than the rest of them, or exhibiting longer than normal service times. -Matt -Original
