Openindiana oi_151a7. zpool with 15x 1TB raidz3 + 2x 8 disk 2TB raidz2.

Many disk operations such as zpool status, creating a new iscsi volume (using sbdadm) etc hangs. Using iostat (-xne) I can determine that two block devices have errors, one is with high probability a cdrom, floppy or such, and the other is a 2TB disk (of one of the raidz2 vdevs the zpool consist of).

iostat -xne
0.0    0.0    0.0    0.0  0.0  0.0    0.0    0.0   0   0   0 1344  22 1366 c10t32d0

The problem with "c9t5000C50057CEF65Fd0" is that it's not listed in 'format'. 'format' further lists all 16 2TB disks, while iostat lists 17. One of the 2TB disks was replaced 2-3 months ago so Im thinking it's possible that iostat still think it's present although its not. Let me point out that I know I have 16 2TB disks physically in the host, and 16 (as 2x8 disk raidz2) in vdevs.

This is a node for backup, so while a reboot is definitely possible it would be very convenient to be able to investigate it further.

Iostat and format in it's entirety:

This is a short answer on a question that is very old and probably already either not an issue any longer or you simply don't care any more. Since I've had the same problem and found a solution for mine I thought I'd answer here.

It's quite simple. add

myIPaddress  myhostname myhostname.FullyQualifiedDomainNameIFIHaveone

In to the /etc/hosts file since for some reason it looks to the resolver library when looking doing a zpool status -v

pool: vmpool03
state: ONLINE
scan: scrub repaired 0 in 0h0m with 0 errors on Fri Dec 16 23:46:02 2016
config:
    NAME                                        STATE     READ WRITE CKSUM
    vmpool03                                    ONLINE       0     0     0
      raidz1-0                                  ONLINE       0     0     0
        scsi-3600508b1001c5189c2e106add2e3b9df  ONLINE       0     0     0
        scsi-3600508b1001c013352baa8831e9b60fb  ONLINE       0     0     0
errors: No known data errors

In my case the difference was before adding the IP and external address 4min till it finished and after, a fraction of a second.

This was done on ZFSonLinux installation with centOS 7.2<

  • Thanks! I do care still and I've had these kinds of issues from time to time, more often than not when disks or hbas not responding. However name resolving sounds like another possible reason, good that you shared it! – 3molo Dec 22 '16 at 13:20
