I afraid, that after real hardware failure (like real HDD death, not these pseudo-broken-hardware situations, when HDDs is perfectly alive and in good condition), all data will be lost. I could restore data from remains of FFS by hands (format is straightforward and well-known), but ZFS is different story... And all these messages about panics after pool import... Yes, it could be result of REAL hardware problems, but I want to have some hope to restore some of the data after such crashes. Yes, backups is solution, but I don't have money to buy (reliable) hardware to backup 4Tb of data :( I attended "Solaris internals" 5-days training four years ago (when I worked for Sun Microsystems), and instructor says same words... --=20 // Black Lion AKA Lev Serebryakov
