Virtual Disk Errors On Systems Running Linux
On some versions of the Linux operating system, the virtual disk size is limited to 1TB. If you create a virtual disk that
exceeds the 1TB limitation, your system may experience the following behavior:
• I/O errors to the virtual disk or logical drive.
• Inaccessible virtual disk or logical drive.
• Virtual disk or logical drive size is smaller than expected.
If you have created a virtual disk that exceeds the 1TB limitation, you must:
1. Back up your data.
2. Delete the virtual disk.
3. Create one or more virtual disks that are smaller than 1TB.
4. Restore your data from backup.
Irrespective of whether your Linux operating system limits the virtual disk size to 1TB, the virtual disk size depends
on the version of the operating system and any updates or modifications that you have implemented. For more
information on operating system, see your operating system documentation.
Problems Associated With Using The Same Physical Disks For Both Redundant And Non-
Redundant Virtual Disks
When creating virtual disks, you should avoid using the same physical disks for both redundant and nonredundant
virtual disks. This applies to all controllers. Using the same physical disks for both redundant and nonredundant virtual
disks can result in unexpected behavior including data loss.
NOTE: SAS controllers do not allow you to create redundant and nonredundant virtual disks on the same set of
physical disks.
