<br>Pretoze si neviem predstavit, ako do GRUB-u alebo LILO-a budem instalovat<br>nejaky ovladac. :)<br>Pravdaze chcem bootovat z RAID5 pola, aby som mal istotu, ze nastartuje<br>pri akejkolvek chybe jedneho disku. Pod akoukolvek chybou myslim aj chybne

<div>no aby som pripomenul, plynule sme presli v diskusii k radicu Adaptec Serial ATA RAID 2410SA (alebo 2810), dufam ze stale hovorime o nom a nie o tom co je v subjecte :)<br> </div>
<div>Ten radic ma podporu vo vanilla kerneli, ako Adaptec AACRAID takze nic ine netreba do kernelu zavadzat. Pri starte sa to tvari takto:</div>

<div>V instalacke Slackwaru je to aj v predkompilovanom kerneli myslim adaptec.s.</div>
<div>Inak mam to ako RAID5, bootuje sa z toho system (v tom pocitaci nie su ine disky, iba tie co su zapojene na ten radic)</div>
<div>V lilo.conf je normalne:</div>
<div>boot = /dev/sda</div>
<div> </div>
<div>Inak co sa tyka tych kvazi-akoze-hardverovych raidov na novych doskach (Promise, a pod.) tak nad tym ani neuvazujte to rozchodit, to je proste uplna katastrofa - lepsie je v tom pripade spravit si normany softverovy raid a je to hadam aj rychlejsie.
