在FAS80x0或AFF80x0上暂时无法读取或写入启动设备后、发生系统中断

适用场景

• FAS80X0
  • FAS8020
  • FAS8040
  • FAS8060
  • FAS8080
• AFF 80 x 0
  • AFF8020
  • AFF8040
  • AFF8060
  • AFF8080

问题描述

• 节点崩溃，其字符串类似于：

Panic string: thread (g_up) on cpu 7 hung for 4001 milliseconds in process g_up on release 9.7P14 (C)

    Panic_Message: g_vfs_done(): rootfs.uzip read error - suspect boot device in process g_up on release 9.8P4 (C)

• 在发生崩溃之前，系统会记录 g_vfs_done 错误：

g_vfs_done():md0.uzip[WRITE(offset=535388160, length=8192)]error = 1
md0.uzip: UZIP(zlib) inflate() failed
g_vfs_done():md0.uzip[READ(offset=40071168, length=4096)]error = 86
vnode_pager_generic_getpages_done: I/O read error 5
md0.uzip: UZIP(zlib) inflate() failed
vm_fault: pager read error, pid 52511 (cat) [retry 9]
md0.uzip[READ(offset=690434048, length=8192)]vm_fault: pager read error, pid 2729 (ucoreman) [retry 9]

• 在自动启动过程中，节点可能会遇到以下情况：

Starting AUTOBOOT press Ctrl-C to abort...
Could not load fat://boot0/X86_64/freebsd/image1/kernel:Device not found
ERROR: Error booting OS on: 'boot0' file: fat://boot0/X86_64/freebsd/image1/kernel (boot0,fat)
Autoboot of PRIMARY image failed. Device not found (-6)
