Hello STH users.
I have some frustrating issues reading from my storage drives.
My server is running Vmware Hypervisor 5.5, with a VM running Solaris 11.1 Cli, with napp-it installed on top.
The issue started after my VMware bootsector got corrupted, and i had to make a new VMware installation.
On import of my VM's they all showed sign of corruption, so i decided to make a clean start, and create new VM's instead of repairing the old ones.
on a fresh install of solaris + napp-it i have no issues importing my pools, and sharing them with SMB to my windows workstation.
Writing data to the storage from my workstation gives no problems either, but reading is almost impossible.
When starting a transfer it starts at the usual 110-120 MB/s, and continues with this speed for 5-10 seconds, then it halves the transferspeed every second, until it is down at xx KB/s, where the transfer is just useless.
Sometimes the transfer also starts at a very low speed, and it never rises in speed again.
The VM performance log shows no sign of the network, cpu, disk or memory being challenged at all.
i ran a DD Bench through napp-it and it shows 498,05 MB/s write and 603,77 MB/s read, with a 12,8GB testfile (the VM has 8 GB Memory atm, while resolving the issue)
all input is much welcomed, and because im not exactly a solaris expert, i might ask some otherwise self-explanatory questions.
