Removing disk from pool

[mvcorrea]

Hi there,
1st post, already searched without an exact match.
System: FreeNAS-9.2.0-RELEASE-x64/

Situation. a 3 disks zpool with a problem in a single disk
I did "zfs set readonly=on Local1" and I think, stabilized the problem
I managed to copy most of the files to an external disk, now I want to remove the defected disk
Now the poll is about 25% used (enough to fit the remaining data in 2 disks).
Any way to put all the data (readable data) in the disks working ok? And remove the defected one?

[root@freenas] /mnt/Local1# zpool status -v Local1
pool: Local1
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

Without having Perl support in free nas(I do perl a lot). I manage to copy most of my files with a Python script ( I've never had programmed in python before), but could help someone in the same situation(suggestions?).

Code:

#!/usr/local/bin/python

import os, re
import datetime
import shutil

#src_dir = "/mnt/Local0/_pictures/"
src_dir = "/mnt/Local0/pict_repetidas/"
dst_dir = "/mnt/DSK/pictures_2014-09/"

logArr = []
errArr = []

def modification_date(filename,count):
    basename = os.path.basename(filename)
    head, tail = os.path.splitext(basename)
    t = os.path.getmtime(filename)
    out = datetime.datetime.fromtimestamp(t)
    #out =head+'{:_%Y%m%d_%H%M%S.%f}'.format(out)+tail
    if(count > 0):
      out =head+'{:_%Y%m%d_%H%M%S}'.format(out)+"-"+str(count)+tail
    else:
      out =head+'{:_%Y%m%d_%H%M%S}'.format(out)+tail
    return out.upper().replace(" ", "_")

def copy_files(src,dst):
    try:
        fileNum = 0
        for root, dirs, files in os.walk(src_dir):
           cnt = 0
           for file_ in files:
              src_ = os.path.join(root, file_)
              fname_ = modification_date(src_, cnt)
              dst_ = dst+fname_
              while(os.path.exists(dst_)):  #rename if already there
                  cnt += 1
                  fname_ = modification_date(src_, cnt)
                  dst_ = dst+fname_
                  errArr.append(src_+ " >>> " + dst_)
              cnt = 0
              shutil.copy(src_, dst_)
              logArr.append(src_ +" >> "+ dst_)
              fileNum += 1
        print "ficheiros processados: "+str(fileNum)
    except (IOError, os.error) as why:
        errArr.append((src_, str(why)))


copy_files(src_dir, dst_dir)

errFile = open("errlog.txt", "w")
for item in errArr:
  errFile.write("%s\n" % item)
errFile.close()


logFile = open("pictlog.txt", "w")
for item in logArr:
  logFile.write("%s\n" % item)
logFile.close()

You have no redundancy. Your only good option is to destroy the pool and restore from backup.

Looks like your ada3p2 also has some bad sectors.
