| Name | Description | Expected Result | Comments (if any) |
|---|---|---|---|
| D0-corruption | 1. Create 128kb file.(f1.txt) 2. Corrupt D0 Stripe. 3. Run Scrub |
D0 should have original un-corrupted content. Parity value should be valid. |
RAID5 with 3 drives |
| D1-corruption | 1. Create 128kb file.(f1.txt) 2. Corrupt D1 Stripe. 3. Run Scrub |
D1 should have original un-corrupted content. Parity value should be valid. |
|
| P-corruption | 1. Create 128kb file.(f1.txt) 2. Corrupt Parity Stripe. 3. Run Scrub |
P should have original un-corrupted content. | |
| D0-D1-corruption | 1. Create 128kb file. (f1.txt) 2. Corrupt both D0 and D1 3. Run Scrub |
Scrub expected to fail and should not recover f1.txt. | should Scrub display/log the filename f1.txt as unrecovered along with failed offset? |
| D0-D1-corruption2 | 1. Create 128kb file. (f1.txt) and another file with size 128kb (f2.txt) 2. Corrupt both D0 and D1 from f1.txt 3. Corrupt only D0 from f2.txt 4. Run Scrub |
Scrub expected not to recover f1.txt. It should recover f2.txt with valid parity. | |
| D1-D3-Corruption | 1. Create 256kb file.(f1.txt) 2. Corrupt D1,D3 Stripe. 3. Run Scrub |
D1,D3 should have original un-corrupted content. Parity value should be valid. | |
| 256kb-P-Corruption | 1. Create 256kb file.(f1.txt) 2. Corrupt P1 Stripe. 3. Run Scrub |
Parity(P1,P2) value should be valid. | |
| 256kb-P2-Corruption | 1. Create 256kb file.(f1.txt) 2. Corrupt both P1,P2 Stripe. 3. Run Scrub |
Parity(P1,P2) value should be valid. | |
| D0-D1-256kb-Corruption | 1. Create 256kb file.(f1.txt) 2. Corrupt D0,D1 Stripe. 3. Run Scrub |
Scrub expected to fail and should not recover f1.txt. Parity (P1,P2) should be valid | |
| D0-D1-256kb-Corruption2 | 1. Create 256kb file.(f1.txt) 2. Corrupt D0,D1,P1 Stripe. 3. Run Scrub |
Scrub expected to fail and should not recover f1.txt. Parity (P2) should be valid | |
