How Can I Handle a Slowdown in Disk Read/Write Speed or Increased I/Os?
Symptom
If you are aware of a service slowdown, depending on if you are examining a Windows or Linux server, you can take the following actions:
- Windows: Open Task Manager and view the average response time.
- Linux: Run iostat -dx to view the I/O performance.
If the disk read/write speed is slowed down, disk I/O increases, or the await time increases, the disk is likely to encounter a performance bottleneck.
Solution
If your disk contains important data, create a new disk from the disk backup, so you do not lose any of the disk data. The procedure is as follows:
- Create a backup for the disk.

- Create a new disk from this backup. During the creation, select a new disk type and configure advanced settings (sharing, SCSI, and encryption) based on your service requirements.
