The default recordsize is 128K. So you are correct, for random reads
performance will be bad as excess data is read. For Oracle it is
recommended
to set the recordsize to 8k. This can be done when creating the filesystem
using 'zfs create -o recordsize=8k '. If the fs has already been
created th
Hi, All,
We have an oracle standby running on zfs and the database recovers very very
slow. The problem is the IO performance is very bad. I find the recordsize
of the ZFS is 128K, and the oracle block size is 8K. My
My question is:
When oracle tries to write a 8k block, will zfs read in 128K and

The problem is this. I have 8 SATA port card. 4 of the slots (0-3) are occupied
with 500 GB drives in a ZFS raid, it is named "ZFSraid1". I now want to buy 5
terabyte drives to create a new ZFS raid, which will have the name "ZFSraid2".
How can I move the data from ZFSraid1 to ZFSraid2 so I can

I have a ZFS raid and wonder if it is possible to move the ZFS raid around from
SATA port to another? Ive heard that someone assembled the SATA connections
differently and the ZFS raid wouldnt work.
Say that I have 8 SATA port controller card with 4 drives in a ZFS raid. Sata
