Sorry that I'm pretty new to these CoW / TI and have some questions would to clarify further.
- What will happens to existing snapshot copies if CoW / TI pool is in "Warning" / "Blocked" status? Are all copies become unusable?
- Snapshot copies will remain usable even CoW / TI pool is in "Shrinking" / "Exceeded Threshold" status right?
- A catastrophic failure on PVOL will also corrupt the VVOL data and restores from the VVOL might not be possible right?
- If the data change rate is high, will restoration of CoW / TI (VVOL to PVOL) faster than ShadowImage (SVOL to PVOL)?
That's all, thank you!
