Hi DCops,
for some reason the analytics1066 megacli LDs don't get the WriteBack settings:
elukey@analytics1066:~$ sudo megacli -LDInfo -Lall -aALL | grep "Cache Policy" Default Cache Policy: WriteBack, ReadAdaptive, Direct, Write Cache OK if Bad BBU Current Cache Policy: WriteThrough, ReadAheadNone, Direct, Write Cache OK if Bad BBU Disk Cache Policy : Disk's Default Default Cache Policy: WriteBack, ReadAdaptive, Direct, Write Cache OK if Bad BBU Current Cache Policy: WriteThrough, ReadAheadNone, Direct, Write Cache OK if Bad BBU Disk Cache Policy : Disk's Default Default Cache Policy: WriteBack, ReadAdaptive, Direct, Write Cache OK if Bad BBU Current Cache Policy: WriteThrough, ReadAheadNone, Direct, Write Cache OK if Bad BBU Disk Cache Policy : Disk's Default Default Cache Policy: WriteBack, ReadAdaptive, Direct, Write Cache OK if Bad BBU Current Cache Policy: WriteThrough, ReadAheadNone, Direct, Write Cache OK if Bad BBU Disk Cache Policy : Disk's Default Default Cache Policy: WriteBack, ReadAdaptive, Direct, Write Cache OK if Bad BBU Current Cache Policy: WriteThrough, ReadAheadNone, Direct, Write Cache OK if Bad BBU Disk Cache Policy : Disk's Default Default Cache Policy: WriteBack, ReadAdaptive, Direct, Write Cache OK if Bad BBU Current Cache Policy: WriteThrough, ReadAheadNone, Direct, Write Cache OK if Bad BBU Disk Cache Policy : Disk's Default Default Cache Policy: WriteBack, ReadAdaptive, Direct, Write Cache OK if Bad BBU Current Cache Policy: WriteThrough, ReadAheadNone, Direct, Write Cache OK if Bad BBU Disk Cache Policy : Disk's Default Default Cache Policy: WriteBack, ReadAdaptive, Direct, Write Cache OK if Bad BBU Current Cache Policy: WriteThrough, ReadAheadNone, Direct, Write Cache OK if Bad BBU Disk Cache Policy : Disk's Default Default Cache Policy: WriteBack, ReadAdaptive, Direct, Write Cache OK if Bad BBU Current Cache Policy: WriteThrough, ReadAheadNone, Direct, Write Cache OK if Bad BBU Disk Cache Policy : Disk's Default Default Cache Policy: WriteBack, ReadAdaptive, Direct, Write Cache OK if Bad BBU Current Cache Policy: WriteThrough, ReadAheadNone, Direct, Write Cache OK if Bad BBU Disk Cache Policy : Disk's Default Default Cache Policy: WriteBack, ReadAdaptive, Direct, Write Cache OK if Bad BBU Current Cache Policy: WriteThrough, ReadAheadNone, Direct, Write Cache OK if Bad BBU Disk Cache Policy : Disk's Default Default Cache Policy: WriteBack, ReadAdaptive, Direct, Write Cache OK if Bad BBU Current Cache Policy: WriteThrough, ReadAheadNone, Direct, Write Cache OK if Bad BBU Disk Cache Policy : Disk's Default
I tried to force it, but nothing happens:
sudo megacli -LDSetProp -ForcedWB -Immediate -Lall -aAll sudo megacli -LDSetProp WB -LALL -aALL
The BBU looks good from what I can see, but I suspect that it might be broken or not working correctly:
