etcd_opts block size is 2300 KiB instead of intended 2300 bytes

Bug

The --etcd_opts code path in fio_run line 1225 sets block_size=2300. The block_size parameter is in KiB throughout the script — it is multiplied by 1024 at line 804:

ios=$(echo "${io_size}*1024" | bc)

This produces bs=2355200 (2,355,200 bytes ≈ 2.25 MiB) in the FIO job file. Real etcd writes are approximately 2.3 KB, so the intended block size was likely 2300 bytes, not 2300 KiB.

Expected Behavior

etcd simulation should use a ~2300-byte block size to match real etcd write patterns.

Notes

There is no straightforward fix without either:

• Adding a special case in loop_block_sizes to skip the *1024 multiplication for etcd, or
• Expressing the value in KiB (approximately 2.25 or rounding to 2), which loses precision.
