устанавливаем новую физическую машину с 10 дисками (кроме диска ОС)
каждый диск на самом деле содержит файловую систему HDFS
после того, как мы установили Linux-машину с комплектом hadoop, мы запустили datanode и заметили множество ошибок из dmesg
так как:
EXT4-fs warning (device sdi): ext4_clear_journal_err:4697: Filesystem error recorded from previous mount: IO failure
EXT4-fs (sdi): warning: mounting fs with errors, running e2fsck is recommended
так как ошибки есть на всем диске (ставим новые 10 дисков)
тогда это не логично, что все диски плохие, что мы подозреваем, это что-то между дисками и HW-машиной
как разъемы, материнская плата и т. д.
я прав со своим выводом?
