Obrázek "nefunguje", aspoň ne u mě.
To už funguje. Docela by se hodil celý výpis dmesg
, nemusím snad připomínat, že je vhodné použít tagy <pre></pre>
Write-back nebo write-through?nastaveno mám Write-back, ale zkoušel jsem i to druhé a výsledek je stejný..
Funguje , ale je to jeden pixel uprostřed :)
Error Message kernel: sdb: asking for cache data failed kernel: sdb: assuming drive cache: write through
Suggested Solution
This error message displays when the Linux Small Computer System Interface (SCSI) mid layer asks for physical disk cache settings. Because the PERC 5 controller firmware manages the virtual disk cache settings on a per controller and a per virtual disk basis, the firmware does not respond to this command. Thus, the Linux SCSI mid layer assumes that the virtual disk's cache policy is write-hrough. SDB is the device node for a virtual disk. This value changes for each virtual disk. See the section Setting Up Virtual Disks for more information about write-through cache. Except for this message, there is no side effect to this behavior. The cache policy of the virtual disk and the I/O throughput are not affected by this message. The cache policy settings for the PERC5 SAS RAID system remain the settings you have already chosen.
